.The `prior_readable_until_ub` parameter is cleared at the end of the peering cycle
Previously, under circumstances when the primary OSD restarted, the knowledge about the prior interval was unavailable as the `prior_readable_until_ub` parameter, which stands for the upper bound on how long prior interval is readable for a PG, was cleared early in the peering stage which was propagated to its peers.
This would cause the placement groups (PGs) to go into a WAIT state and this would block any OSD request during that period.
With this release, the `prior_readable_until_ub` parameter is cleared at the end of the peering cycle, just before activating, after communicating to the peer OSDs and the PGs no longer go into WAIT state after the OSD is restarted.
