* Add providers subcommand to verify providers Allows users to check what providers are available * Fix version output to add new line This command was totally broken until we moved around the call to `initConfig()`, this just fixes the output now that it works. * Flip boolean of provider include tags All providers are still included by default and fix tags using the old format.
