qa: support running under non privileged user

If the test is run against a cluster started with vstart.sh (which is
the case for make check), the --asok-does-not-need-root disables the use
of sudo and allows the test to run without requiring privileged user
permissions.

OSD: wake_pg_waiters after dropping pg lock

Otherwise, we dispatch_session_waiting while still holding the pg lock,
which is obviously wrong.  Unfortunately, this places an additional
burden on any user of _create_lock_pg, but I think it's unavoidable
since that method must atomically add the pg to the map and lock it.

mon: clear osd request queue latency info on down or up

It doesn't make sense to warn about slow requests on OSDs that are down;
clear those stats in the monitor when we see an OSD go down (or up).
