    osd: add log for pg peering and activiting complete

    This log is added to PeeringState::Active::react(const AllReplicasActivated &evt)
    to pair with the PeeringState::start_peering_interval() log,
    So that under the default log level of debug_osd(1/5),
    the completion of each pg peering can be traced back through ceph-osd.x.log

    Because under some exceptions, we need to know clearly
    whether pg has completed peering at the time when the exception occurs,
    and whether it can handle client IO.

PeeringState::start_peering_interval()   ///This is the log of the original pg peering start
{
  psdout(1) << __func__ << " up " << oldup << " -> " << up
        << ", acting " << oldacting << " -> " << acting
        << ", acting_primary " << old_acting_primary << " -> "

        << ", features acting " << acting_features
        << " upacting " << upacting_features
        << dendl;
}

PeeringState::Active::react(const AllReplicasActivated &evt)  ///This is the log of the newly added pg peering->activating->active end
{
  psdout(1) << __func__ << " AllReplicasActivated : Peering->Activating->Active over" 
        << " PG_STATE_ACTIVE=" << ps->state_test(PG_STATE_ACTIVE)
        << " PG_STATE_WAIT=" << ps->state_test(PG_STATE_WAIT)
        << " PG_STATE_PEERED=" << ps->state_test(PG_STATE_PEERED)
        << " last_epoch_started=" << ps->info.last_epoch_started
        <<dendl;
}

The purpose of adding this part of the log: it is convenient to locate the log time from the start to the end of a single pg peering
