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.
