Fix --quiet being used with nested subcommands.

This fixes an issue where `--quiet` doesn't work with commands that have
subcommands. This is because `config_configure` only looks at the global
and top-level subcommand, and not deeper subcommands. The issue was that
`--quiet` was not defined as a global flag. This was changed in
rust-lang#6358 in order to give a better
help message for `cargo test --quiet`. I don't remember if clap just
didn't support overriding at the time, or if we just didn't know how it
worked. Anyways, it seems to work to override it now, so I think it
should be fine to mark it as global.

This should bring in `--quiet` more in-line with how `--verbose` works.
This means that `--quiet` is now accepted with `cargo report`,
`cargo help`, and `cargo config`.

This also fixes `--quiet` with `cargo clean gc`.

This should also help with supporting `--quiet` with the new `cargo
owner` subcommands being added in
rust-lang#11879.

Fixes rust-lang#12957
