Add a note about waiting to collect data
Users might initially be confused that immediately after deployment, the
dashboard looks broken. This is because it doesn't yet have the data it
needs to function.

ansible: Do not enable rhsm repos
We are shipping as a regular product and as such, we cannot enable
additional repos via rhsm. The customers might even not have these repos
installed (especially the storage console repo might not be available to
them).
If we need any of the packages from these repos, we need to cross-ship
them in our product (as we already do downstream).

mon: simplify the admin_socket read logic
The initial commit placed logic in each area that called the admin
socket. This patch separates the admin socket call out to a separate
method, so it gets checked in one place.

rgw: look for the admin_socket on each call
The admin_socket name for rgw is not fixed, unlike mon/osds. Therefore
to account for svc restarts and name changes the socket name is
determined at each get_stats cycle. If the socket isn't there, the
collector just passes back the version of radosgw to the caller and
will send stats again once a socket is detected on the host

mon: account for null dict from _admin_socket
the _admin_socket method could return a null dict if the
socket is not there (i.e. ceph-mon is down). By checking for the
empty dict, the collector can remain active while ceph-mon is
stopped and restarted during normal maintenance processes on a
host.
