osd/PrimaryLogPG: fix potential pg-log overtrimming

In https://github.com/ceph/ceph/pull/21580 I set a trap to catch some wired
and random segmentfaults and in a recent QA run I was able to observe it was
successfully triggered by one of the test case, see:

```
http://qa-proxy.ceph.com/teuthology/xxg-2018-07-30_05:25:06-rados-wip-hb-peers-distro-basic-smithi/2837916/teuthology.log
```

The root cause is that there might be holes on log versions, thus the
approx_size() method should (almost) always overestimate the actual number of log entries.
As a result, we might be at the risk of overtrimming log entries.

https://github.com/ceph/ceph/pull/18338 reveals a probably easier way
to fix the above problem but unfortunately it also can cause big performance regression
and hence comes this pr..

osd/PrimaryLogPG: avoid dereferencing invalid complete_to

For the auto-repair (EIO caused) case, we will not reinitialize
**complete_to** (because last_complete is equal to last_update!)
and hence there is chance that **complete_to** should aleady
point to **log.end()** before we call recover_got.

We could simply drop it here as we (already) logged the **complete_to**
iterator change in a more compatible way a few lines below.

osd/PrimaryLogPG.cc: limit trimming at can_rollback_to

This change is motivated by the failures seen in the multimds suite,
where we hit assert(s <= can_rollback_to), while trimming the log in ec
pools.

This is due to the fact that we had removed limits on the trim_to value to
address https://tracker.ceph.com/issues/23979.

But, seems that this could be dangerous for ec pools. So, keep the
can_rollback_to limit, while calculating the trim_to value.

src/osd/PG.cc: remove redundant call to trim_log()

This change is motived by the failure tracked in
https://tracker.ceph.com/issues/25198. The failure highlights a case, when a
call to trim_log() after the PG has recovered, races with the previous op,
on a replica OSD. Since the previous operation has not completed, the
last_complete value for that OSD is not valid, when we try to trim the
log. It is also worth noting that the race is due to MOSDPGTrim going through
the strict queue as a peering message vs regular ops going through the
non-strict queue.

During the investigation of this bug, we noticed that, with
https://tracker.ceph.com/issues/23979, we allow pg log trimming to
happen on the primary and replicas, whenever we cross the upper bound of
the pg log. This also ensures that pg log trimming happens while processing
any new op.

Therefore, the function trim_log(), which earlier served the purpose of
trimming logs on the primary and replicas, just before the PG went into
the Recovered state, is no more required. This acted like a last line of
defense to trim logs, when we did not need the logs any more. But, this call
seems redundant now, because, we are limiting the pg log length at all times.

qa/tasks/thrashosds-health.yaml: whitelist 'slow request'

https://github.com/ceph/ceph/pull/25824 adds slow request to OSD logs.
To deal with it, whitelist 'slow request' instead of 'slow requests'.
This PR is specific to luminous because later versions whitelist it correctly.

client: fix fuse client hang because its pipe to mds is not ok

If fuse client session had been killed by mds and the mds daemon restart
or hot-standby switch happens right away but the client did not receive
any message from monitor due to network or other whatever reason untill

lead the seession still is STATE_OPEN but client can't send any message to
mds because its pipe is not ok.So we should close the stale session so that
it can be reopened again.
