mimic and luminous baselines

In preparation for QE validation I ran limited (10 jobs) baselines for luminous and mimic: http://pulpito.ceph.com/?branch=wip-yuri-luminous_10.22.19 http://pulpito.front.sepia.ceph.com/?branch=wip-yuri-mimic_10.22.19 Dev lead, pls scan thru those to address issues before we start more testing pls. There are issue possible py3 issues (https://tracker.ceph.com/issues/42292) and possible msd crashes (https://tracker.ceph.com/issues/42491) Thx YuriW
