Correct gnocchi-upgrade command quotes

After merging commit 488796, single quotation marks
were missed. This causes the upgrade to fail as the
flag --sacks-number is considered a su command flag.

Also mounts Ceph config data into the container which
seems needed for the gnocchi-upgrade command when
configured to use Ceph.

Also move the gnocchi db sync to step 4, so ceph is
ready. Add a retry loop to ceilometer-upgrade cmd so
it doesnt fail while apache is restarted.
