Stack update fails on RHEL if nodes are unsubscribed to Ceph OSD RHN channel

[Giulio Fidente]

On RHEL the Ceph packages are distributed using three different software channels, Ceph MON, Ceph OSD and Ceph Tools.

Yum update fails on nodes not subscribed to the Ceph OSD channel because puppet-ceph enforce update of ceph-base, ceph-mon and ceph-osd packages.

Change abandoned by Giulio Fidente (<email address hidden>) on branch: master
Review: https://review.openstack.org/498240
Reason: we'll include this in I7a581518ed25cf5f264abfaabfcf2041363a065b instead which is also needed to fix pre-existing deployments

I think this has been fixed in https://review.openstack.org/#/c/496921/ but needs to be backported

    Maintain ceph-osd package only on nodes hosting CephOSD service

    The ceph-osd package is only required on nodes hosting the CephOSD
    service, but the package's presence on other nodes may interfere with
    software updates. That's because some distros distribute Ceph software
    in different channels, and not all nodes have access to the ceph-osd
    channel.

    There are two parts to the fix, and the first is an enhancement to the
    yum update process. The process detects when the ceph-osd package is not
    required, and removes the package from the node.

    The second part takes ceph-osd out of the default list of packages
    needed by puppet-ceph. The ceph-osd package is listed only on the nodes
    hosting the CephOSD service.
