Fails to create alarm with trust URL action

[Thomas Herve]

Tried this on master:

$ ceilometer alarm-create --name alarm1 --alarm-action trust+http://localhost:1234/ -m cpu --threshold 1
'NoneType' object has no attribute 'user_id' (HTTP 500) (Request-ID: req-19b78842-1f95-431d-9be6-eb4868a80573)

The traceback:

Presumably the session refactoring went wrong.

    Properly retrieve keystone user from admin client

    When using sessions, we need to get the user from the session instead of
    the auth plugin directly. This fixes an issue when creating alarms with
    trusts.
