* Load tracing filter only from config and simplify logic.
* Configure the state storage in the config, not an environment variable.
This also changes the config so that the path is always set rather than being
optional, because Zebra always needs a place to store its config.
Each subsection has to have `serde(default)` to get the behaviour we want
(delete all fields except the ones that have been changed); otherwise, we can
delete only entire sections.
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`.
* 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.
