Description of problem: Since cinder doesn't emit 'snapshot.update.(start|end)' notifications, ceilometer's code that handles them is doing nothing. IMHO, we don't need this code part until cinder emits notifications.
Fixed landed in liberty https://review.openstack.org/182104
Verified in 5.0.0-2.el7ost
