currently enabling audit middleware results in every request producing
warning in the log 'Invalid uuid: ' from pycadf,
due to audit middleware not being able find a uuid to set as a
service/target id because auth_token middleware no longer does not pass ids of the endpoints to the catalog it sets on request.
This patch adds service id to the catalog being set by auth_token,
and uses it in audit middleware too. This will hopefully not
dramatically increase the size of the catalog.
