Don't run ceilometer-upgrade via upgrade_tasks

This needs to be run by puppet or ansible runs it as root and the
later run by puppet fails due to permissions on the logfile.

Probably we need to remove the *sync calls for most services to
avoid similar issues, now that we're running puppet as part of the
pre-converge upgrade process but that will be done in another patch.
