This makes all tower subcrates have the following lints as warn (rather
than allow): `missing_docs`, `rust_2018_idioms`, `unreachable_pub`, and
`missing_debug_implementations`. In addition, it consistently applies
`deny(warning)` *only* under CI so that deprecations and macro changes in minor
version bumps in dependencies will never cause `tower` crates to stop
compiling, and so that tests can be run even if not all warnings have been
dealt with. See also https://github.com/rust-unofficial/patterns/blob/master/anti_patterns/deny-warnings.md
Note that `tower-reconnect` has the `missing_docs` lint disabled for now
since it contained _no_ documentation previously. Also note that this
patch does not add documentation to the various `new` methods, as they
are considered self-explanatory. They are instead marked as
`#[allow(missing_docs)]`.
Calling a method on `Pin<&mut Self>` moves the pin, which means you can't call more methods later. The solution to this is to use `Pin::as_mut`. But it's annoying to have to do that to _every_ call to the `assert_request_eq!` helper macro from `tower-test`, so I made it do it for me.
* Consolidate `limit` layers
- `InFlightLimit` and `RateLimit` are moved into `tower-limit` crate.
- `InFlightLimit` is renamed to `ConcurrencyLimit`.
