`tower` builds are now failing on CI because Tokio v1.17.0 bumped MSRV
to 1.49.0. This branch updates `tower`'s MSRV to 1.49.0 to track Tokio's
MSRV. I also added nicer documentation of the MSRV based on Tokio's, and
added the `rust-version` Cargo metadata to the `tower` crate's
`Cargo.toml`.

Note that `tower-service` and `tower-layer` can technically continue to
support much earlier Rust versions than `tower` can, since they don't
depend on external crates and are very small. We could consider testing
separate, older MSRVs on CI for those crates individually. I didn't do
that in this PR, though, because I wasn't sure if this was worth the
effort and I just wanted to get CI passing again.

Tower

Tower is a library of modular and reusable components for building robust networking clients and servers.

Overview

Tower aims to make it as easy as possible to build robust networking clients and servers. It is protocol agnostic, but is designed around a request / response pattern. If your protocol is entirely stream based, Tower may not be a good fit.

Supported Rust Versions

Tower will keep a rolling MSRV (minimum supported Rust version) policy of at least 6 months. When increasing the MSRV, the new Rust version must have been released at least six months ago. The current MSRV is 1.49.0.
