    Make sure create ceilometer alarm successful

    If enable re-auth, we will use the stored context
    instead of request context, then we can't create
    ceilometer alarm resource. There are two problems
    when create ceilometer client:
    1. the stored context has no domain info, an error
    raised from keystone: BadRequest: Expecting to find
    domain in project. So this patch will retrive the
    user/project domain ids from the auth_ref.
    2. after fix the first problem, then another error
    raised from keystone: Forbidden: You are not authorized
    to perform the requested action. Due keystone doesn't
    allow to create a token by a trust-scoped token when
    get aodh endpoint. So this patch will pass 'aodh_endpoint'
    to ceilometer client to avoid this.
