  Implement this behaviour in the application layer of your OAuth / OpenID Connect provider.
  This behaviour gives all callbacks triggered invoking `Boruta.Oauth` module functions.

  > __Note__: This behaviour is splitted into `Boruta.Oauth.AuthorizeApplication`, `Boruta.Oauth.TokenApplication`, `Boruta.Oauth.IntrospectApplication`, and `Boruta.Oauth.RevokeApplication` providing utilities to implement the different OAuth / OpenID Connect endpoints independently.
