Upgrade path to Luminious needed

[Corey Bryant]

ceph and ceph-mon need upgrade path to Luminous for Pike.

From wolsen:

If the UPGRADE_PATHS gets a "jewel": "luminous" mapping and the UCA_CODENAME_MAP gets a 'pike': 'luminous' mapping... I think it generally will d.t.r.t - though you may want to add the bootstrap of the mgr cluster into the upgrade_monitor code path rather than in the charms. https://github.com/openstack/charms.ceph/blob/master/ceph/__init__.py#L1584

Let's try to get a mojo spec together as part of this to upgrade ceph charms. There's also an existing upgrade spec for openstack services that should also be updated to upgrade ceph.

[Ryan Beisner (1chb1n)]

Indeed. We should do 2 specs:

#### openstack upgrade spec
We have an OpenStack Upgrade mojo spec, but it does not currently upgrade ceph itself IIRC. We should change that so that ceph is also upgraded.

#### ceph upgrade spec
We should take a basic ceph cluster and upgrade it. This can be based on one of the existing basic ceph specs.

If at all possible, it'd be great to do the Ceph upgrade mojo-spec with multiple disks per node and with data loaded into the cluster.
