With the 1.1 release we should not be creating bluestore OSDs
with rook's legacy partitioning scheme. All new bluestore OSDs
should be created with ceph-volume. Therefore, the miminum
version allowed is a version of mimic supporting ceph-volume.

This commit also adds consistent version checking between
the Add and Update methods for the operator handling the
CR events.
