crimson/os/seastore: set journal_tail_target during replay

This is a bug fix, otherwise if crimson-osd boot up multiple times without
filling up more than one segment, segments may be used up and can't be
reclaimed as they would have the same journal tail

qa/tasks/rook: add OSD creation to Rook QA

This commit adds OSD creation to the Rook QA tasks. The Rook task will
explicitly wait for the mgr to start and the CLI to work (instead of
implicitly doing so while waiting for 'ceph osd dump' to work).
Then it will do `ceph orch apply osd --all-available-devices` to create
OSDs on the rest of the PVs.
