* fix(ci): sentry is not longer being activated in test builds
This removes sentry from all the test execution, as some tests might fail as sentry wasn't initially built, or it might take more time to build as it will have to build with sentry.
* fix(build): workaround the failed to fetch oauth token error
* Drop sentry dependencies when enable-sentry feature is disabled
* Make lightwalletd gRPC tests depend on a new lightwalletd-grpc-tests feature
* fix(ci): remove enable-sentry feature from tests
* Add lightwalletd-grpc-tests feature for functionality or efficiency
And document where it is just used to stop re-compilations.
* Remove redundant `cmake` and `protobuf-compiler` dependencies
* Document Zebra's optional production and test feature flags
* Minimise dependencies in zcash-params/Dockerfile
* Minimise dependencies in docker/Dockerfile

* Update changelog for 1.0.0-beta.8
* Bump Zebra crate versions
The tower crates and their dependencies haven't changed,
so their versions don't need to be bumped.
Some Zebra crates haven't changed,
but I bumped all the versions to keep them consistent.

* Avoid sequential borrows in `LatestChainTip`
Calling `watch::Receiver::borrow` more than once in the same scope can
cause a deadlock. The instrumented methods were calling `borrow` twice
to record instrumented fields.
This refactors things to ensure `borrow` is only called once to record
the fields and perform any actions with the chain tip block.
* Remove `borrow()` calls in `ChainTipChange`
Refactor to use a `LatestChainTip` instance instead, which safely
protects the internal `watch::Receiver` so that it is not borrowed more
than once in the same scope.
* Add a paragraph to the Asynchronous guide
Warn against using two borrow guards in the same scope, and describe why
that can lead to a deadlock.
* Draft design for lightwalletd database support
* Explain how to create blocks from headers and transactions
* Make keys smaller to improve database performance
