Switch Ceilometer default backend to MySQL
MongoDB 2.4 not being available in Ubuntu cloud archive for a while now,
and the catch up done by this driver allows me to think it might be a
good idea to switch by default on SQL for now on devstack.
We can add another job to have Ceilometer tested on MongoDB too later.
