The goal of this extension is to allow third-party service providers
to acquire tokens with a limited subset of a user's roles for acting
on behalf of that user. This is done using an oauth-similar flow and
api.
The API looks like::
# Basic admin-only consumer crud
POST /OS-OAUTH1/consumers
GET /OS-OAUTH1/consumers
PATCH /OS-OAUTH1/consumers/$consumer_id
GET /OS-OAUTH1/consumers/$consumer_id

GET /users/{user_id}/OS-OAUTH1/access_tokens
/{access_token_id}/roles/{role_id}
DELETE /users/$user_id/OS-OAUTH1/access_tokens/$access_token_id
# OAuth interfaces
POST /OS-OAUTH1/request_token # create a request token
PUT /OS-OAUTH1/authorize # authorize a request token
