upgrade: fix upgrade jewel to luminous for mgr nodes
upgrade: fix upgrade jewel to luminous for mgr nodes

mgr nodes can't be upgraded from jewel to luminous because ceph-mgr role
is skipped because of the condition `when:
"ceph_release_num[ceph_release] >= ceph_release_num.luminous"`. Indeed,
ceph-mgr package is upgraded in `ceph-mgr` role, therefore,
`ceph_release` is still set to the old version. It means the when can't
be satisfied.
