Oopsie, I forgot to add oauth.permissions.yml in my previous commit.

Wrapped the whole logic to authenticate in a try-catch since OAuthConsumer() can throw OAuthException too.

Integrated oauth_consumer table with request authentication.

Added basic UI to create and delete OAuth Consumers.
Pending to integrate them with the OAuthProvider.

Changed field name by description. Will see if it can be edited in-place at the listing.

OAuth consumers can now be added and listed within a Drupal user account.

TODO:
* Edit and delete consumers.
* Verify consumer keys in a request against oauth_consumer table.

Removed all Drupal 7 files not needed by this module at the moment.

Added base controller and form to list and add consumers.

Removed enable_provider setting since OAuth will just be a provider. At least for the moment.

Ported info file.

Moved sub-module files to modules/oauth_providerui under OAuth's module directory.
