Don't use test gnocchi its not stable

for some strange reason when installing ceilometer and gnocchi
the mysqld process is killed by the oom killer of the operating system
this happens only in the gate and not localy on my devstack.

for now we won't enable the ceilometer plugin (which installs gnocchi)
