qa/tasks/ceph.py: populate mnt_point in hammer

In hammer, there is no "mnt_point" variable, yet 53225d5 was cherry-picked to
hammer - see 87e0299448908775600c62130617bad503027768 and https://github.com/ceph/ceph/pull/12455

This caused lots of "NameError: global name 'mnt_point' is not defined" errors
in hammer integration testing.

This is not a cherry-pick, because the mnt_point variable was introduced by
a54ff597faa379c8fd369352fb924651be269f95 ("tasks/ceph: convert cluster creation
to work with multiple clusters") which was not backported to hammer.

Thrasher: log backtrace of thrown exception

* add a wrapper to log uncaught exception to self.logger, greenlet also
  prints the backtrace and exception to stderr, but teuthology.log does
  not capture stderr. so we need to catch them by ourselves to reveal
  more info to root-cause this issue.
* log uncaught exception thrown by Thrasher.do_thrash() to self.log.

hammer: ObjectCacher: fix bh_read_finish offset logic

If we have an incoming read split across multiple BufferHeads, we want to
line up the BufferHead's bl with the incoming OSDOp's bl at the right offset. We
were erroneously using this nonsense calculation (always equal to zero!) when
a much simpler comparison of the BufferHead's logical object offset to the
incoming OSDOp's logical offset will do the trick nicely.

prior to this change, we sends monmap when serving the subscription

so we need to send latest monmap to subscribes and update the
