we have osd_min_pg_log_entries to 2 (good) but not osd_pg_log_trim_min
which defaults to 100. Thus, even on those tests we're only rarely vulnerable.
Reset osd_min_pg_log_entries to 0 to make sure we really
keep a minimal pg log in hand.

Due to http://tracker.ceph.com/issues/18309 the pid file for fuse clients
should always be set to the empty string. (Teuthology's default ceph.conf
sets it to /var/run/ceph/$cluster-$name.pid)
This commit adds a reusable yaml facet for this purpose.
