* add zebrad acceptance tests
* add custom command test helpers that work with kill
* add and use info event for start and seed commands
* combine conflicting tests into one test case

* Flatten consensus::verify::* to consensus::*
* Move consensus::*::tests into their own files
* Move CheckpointList into its own file
* Move Progress and Target into a types module
QueuedBlock and QueuedBlockList can stay in checkpoint.rs, because
they are tightly coupled to CheckpointVerifier.
* also download tips and filter tips
* dispatch all block downloads together
* tweek to match henry's changes
* switch to more intuitive match

Prior to this change, the service returned by `zebra_network::init` would spawn background tasks that could silently fail, causing unexpected errors in the zebra_network service.
This change modifies the `PeerSet` that backs `zebra_network::init` to store all of the `JoinHandle`s for each background task it depends on. The `PeerSet` then checks this set of futures to see if any of them have exited with an error or a panic, and if they have it returns the error as part of `poll_ready`.
The components are accessed by a lock on application state. When some command
calls block_on to enter an async context, it obtained a write lock on the
entire application state. This meant that if the application state were
accessed later in an async context, a deadlock would occur. Instead the
TokioComponent holds an Option<Runtime> now, so that before calling block_on,
the caller can .take() the runtime and release the lock. Since we only ever
enter an async context once, it's not a problem that the component is then
missing its runtime, as once we are inside of a task we can access the runtime.
* Add a TracingConfig and some components

* Restructure, use dependency injection, initialize tracing
* Start a placeholder loop in start command
* Add hyper alpha.1, bump tokio to alpha.4
* Hello world endpoint using async/await from hyper 0.13 alpha
Also cleaned up some linter messages.

* Update to tracing_subscriber 0.1
* fmt
* add rust-toolchain
* Remove hyper::Version import
* wip: start filter_handler impl
* Add .rustfmt.toml
* rustfmt
* Tidy up .rustfmt.toml
* Add filter reloading handling.
* bump toolchain
* Remove generated hello world acceptance tests.
These test the behaviour of the autogenerated binary and work as examples of
how to test the behaviour of abscissa binaries. Since we don't print "Hello
World" any more, they fail, but we don't yet have replacement behaviour to add
tests for, so they're removed for now.
* Clean up config file handling with Option::and_then.
