* fix: Use the correct conditions and merge method
Mergifys Status Checks conditions are based on the job name, not the worflow name. As our worflows have dynamic names, each variant must be considered.
Squash merges are the default being used in the Zebra repo, so mergify must comply with this configuration.
Use condition operators for labels in each pull request rule; previously it was expecting both labels to be set. And update names accordingly.
* fix: Allow mergify to merge dependabot PRs
Also adapt dependabot's configuration to use the recently adapted labels

* Refactor to create heartbeat sender function
Move the code that's part of the heartbeat task into a separate helper
function.
* Move `Client` initialization down
Keep it closer to where it's actually used, and make it easier to add
new fields to `Client` for the connection and heartbeat tasks.
* Add background task handles to `Client` type
Prepare it to be able to check for panics or errors from the background
tasks.
* Add dummy background tasks to `ClientTestHarness`
Spawn simple timeout tasks as mock connection and heartbeat tasks.
* Fix `PeerSet` tests that use `ClientTestHarness`
Building a `ClientTestHarness` requires a Tokio runtime to be set up, so
the calls were moved into the `async` block.
* Refactor to create `set_task_exited_error`
Make the code reusable for both background tasks.
* Check heartbeat task for errors
Periodically poll it to check if the task has unexpectedly stopped.
* Check if connection background task has stopped
The client service should stop if the connection background task has
exited, because then it's not able to receive any replies.
* Allow aborting mocked `Client` background tasks
Wrap the background tasks in `Abortable`, so that they can be aborted
through the `ClientTestHarness`.
* Test if stopped connection task is detected
Check that stopping the background connection task is something that the
`Client` instance detects and handles correctly.
* Test if stopped heartbeat task is detected
Check that stopping the background heartbeat task is something that the
`Client` instance detects and handles correctly.
* Allow setting custom background tasks
Will be used later to create background tasks that panic.
* Test if `Client` handles panics in connection task
Use a mock background connection task that panics immediately, and check
that the `Client` handles it gracefully.
* Test if `Client` handles panics in heartbeat task
Use a mock background heartbeat task that panics immediately, and check
that the `Client` handles it gracefully.
* Change ticket referenced by `TODO`
The previously linked issue was a broad plan to improve Zebra's shutdown
behavior, while the new issue is more specific, and can be scheduled
sooner.

* Move `MockedClientHandle` to `peer` module
It's more closely related to a `Client` than the `PeerSet`, and this
prepares it to be used by other tests.
* Rename `MockedClientHandle` to `ClientTestHarness`
Reduce confusion, and clarify that the client is not mocked.
Co-authored-by: teor <teor@riseup.net>
* Add clarification to `mock_peers` documentation
Explicitly say how the generated data is returned.
* Rename method to `wants_connection_heartbeats`
The `Client` service only represents one direction of a connection, so
`is_connected` is not the exact term.
Co-authored-by: teor <teor@riseup.net>
* Mock `Client` instead of `LoadTrackedClient`
Move where the conversion from mocked `Client` to mocked
`LoadTrackedClient` in order to make the test helper more easily used by
other tests.
* Use `ClientTestHarness` in `initialize` tests
Replace the boilerplate code to create a fake `Client` instance with
usages of the `ClientTestHarness` constructor.
* Allow receiving requests from `Client` instance
Create a helper type to wrap the result, to make it easier to assert on
specific events after trying to receive a request.
* Allow inspecting the current error in the slot
Share the `ErrorSlot` between the `Client` and the handle, so that the
handle can be used to inspect the contents of the `ErrorSlot`.
* Allow placing an error into the `ErrorSlot`
Assuming it is initially empty. If it already has an error, the code
will panic.
* Allow gracefully closing the request receiver
Close the endpoint with the appropriate call to the `close()` method.
* Allow dropping the request receiver endpoint
Forcefully closes the endpoint.
* Rename field to `client_request_receiver`
Also rename the related methods to include
`outbound_client_request_receiver` to make it more precise.
Co-authored-by: teor <teor@riseup.net>
* Allow dropping the heartbeat shutdown receiver
Allows the `Client` to detect that the channel has been closed.
* Rename fn. to `drop_heartbeat_shutdown_receiver`
Make it clear that it affects the heartbeat task.

* Move `NowOrLater` into a new `now-or-later` crate
Make it easily accessible to other crates.
* Add `IsReady` extension trait for `Service`
Simplifies checking if a service is immediately ready to be called.
* Add extension method to check for readiness error
Checks if the `Service` isn't immediately ready because a call to
`ready` immediately returns an error.
* Rename method to `is_failed`
Avoid negated method names.
Co-authored-by: teor <teor@riseup.net>
* Add a `IsReady::is_pending` extension method
Checks if a `Service` is not ready to be called.
* Use `ClientTestHarness` in `Client` test vectors
Reduce repeated code and try to improve readability.
* Create a new `ClientTestHarnessBuilder` type
A builder to create test `Client` instances using mock data which can be
tracked and manipulated through a `ClientTestHarness`.
* Allow configuring the `Client`'s mocked version
Add a `with_version` builder method.
* Use `ClientTestHarnessBuilder` in `PeerVersions`
Use the builder to set the peer version, so that the `version` parameter
can be removed from the constructor later.
* Use a default mock version where possible
Reduce noise when setting up the harness for tests that don't really
care about the remote peer version.
* Remove `Version` parameter from the `build` method
The `with_version` builder method should be used instead.
* Fix some typos and outdated info in the release checklist
* Add extra client tests for zero and multiple readiness checks (#3273)
And document existing tests.
* Replace `NowOrLater` with `futures::poll!` (#3272)
* Replace NowOrLater with the futures::poll! macro in zebrad
* Replace NowOrLater with the futures::poll! macro in zebra-test
* Remove the now-or-later crate

* Create a strategy for block heights after Sapling
Provides an arbitrary network (mainnet or testnet) and a block height
between the Sapling activation height on that network and the maximum
block height.
* Create a helper function to select block heights
Allows generating block heights inside a range using a scale factor
between 0 and 1.
* Allow specifying the outpoint index for mock UTXOs
Avoid creating multiple transparent transfers in the same transaction
with the same source UTXO, which would lead to a double spend.
* Create helper function to mock multiple transfers
Given relative block height scale factors, create a mock transparent
transfer for each one of them.
Also add a constant that serves as a guideline for the maximum number of
transparent transfers to mock.
* Create helper function to sanitize tx. version
Make sure the arbitrary transaction version is valid for the network
(testnet or mainnet) at the specified block height.
* Create `mock_transparent_transaction` helper func.
Creates a V4 or V5 mock transaction that only includes transparent
inputs and outputs.
* Create helper function for transaction validation
Performs the actual tested action of verifying a transaction. It sets up
the verifier and uses it to obtain the verification result.
* Test if zero lock time means unlocked
Generate arbitrary transactions with zero lock time, and check that they
are accepted by the transaction verifier.
* Allow changing the sequence number of an input
Add a setter method for a `transparent::Input`'s sequence number. This
setter is only available for testing.
* Test if sequence numbers can disable lock time
Create arbitrary transactions and set the sequence numbers of all of its
inputs to `u32::MAX` to see if that disables the lock time and the
transactions are accepted by the verifier.
* Test block height lock times
Make sure that the transaction verifier rejects transactions that are
still locked at a certain block height.
* Test block time lock times
Test that the transaction verifier rejects a transaction that is
validated at a block time that's before the transaction's lock time.
* Test unlocking by block height
Test that transactions unlocked at an earlier block height are accepted
by the transaction verifier.
* Test transactions unlocked by the block time
Test that transactions that were unlocked at a previous block time are
accepted by the transaction verifier.
* Fix an incorrect method comment
