Simonas Kazlauskas d385601433 --all-features and --no-default-features ...

This adjusts the code and documentation for `--all-features` and
`--no-default-features` to work correctly. With `--no-default-features`
no `DefaultAuthenticator` is made available. Users are in control of
picking the `Connector` they want to use, and are not forced to stomach
a dependency on `rustls` or `hyper-tls` if their TLS implementation of
choice doesn't happen to match one of the two.

To indicate this, the unstable `doc_cfg` feature is used to build
documentation on docs.rs. That way the generated documentation has
notices on these types that look as such:

> This is supported on crate features hyper-rustls or hyper-tls only.

Additionally this functionality is tested via additional coverage in the
Actions' CI.
