Michael Mayer 467f7b1585 OAuth2: Add Client Credentials Authentication #213 #782 #808 #3730 #3943
This adds standard OAuth2 client credentials and bearer token support as
well as scope-based authorization checks for REST API clients. Note that
this initial implementation should not be used in production and that
the access token limit has not been implemented yet.
