Clean up the Provider class a bit more

[dkotter]

Is your enhancement related to a problem? Please describe.

With the refactoring done in #611, we know have Features as our main piece of functionality, with each Feature being powered by one or more Providers.

While some cleanup was done on the base Provider class, I think there's still things in there that used to be functional that are no longer needed (and may no longer even be used).

For instance, thinking any reference to settings (like the get_settings method) don't need to be there any longer as settings are now handled at the Feature level.

There may be other things in there as well, so just need to do a quick scan and cleanup.
