Bug 1857279 - Load @SettingsProvider
settings early so that we can parse set aliases and load the correct virtualenv r=ahal
Aliased commands have not loaded the virtualenv associated with a command/subcommand since bug 1695312. It has been defaulting to the `common` virtualenv, which worked most of the time since most commands use `common` and it also contains a large share of our dependencies.
