The PS updates queries in wait_for_pgs function in ceph-client and
ceph-osd charts. It allows more accurately check the status of PGs.
The output of the "ceph pg ls" command may contain many PG statuses,
like "active+clean", "active+undersized+degraded", "active+recovering",
"peering" and etc. But along with these statuses there may be such as
"stale+active+clean". To avoid the wrong interpretation of the status
of the PSs the filter was changed from "startswith(active+)" to
"contains(active)".
Also PS adds a delay after restart of the pods to post-apply job.
It allows to reduce the number of useless queries to kubernetes.
