This is not very useful at this level:
 - we see it from 'orch ps'
 - it can be a mix of ids during upgrade
 - some services may have multiple images at steady state (e.g., ingress)

If there is no osdspec_affinity or service_name (from unit.meta), then
report as 'osd.unmanaged'.

The prior implementation first tried to fabricate services based on the
running daemons, and then filled in defined services on top.  This led
to duplication and a range of small errors.

Instead, flip this around: start with the services that are defined,
and only fill in 'unmanaged' services where we need to.

Drop the osd kludges and instead rely on DaemonDescription.service_id to
return the right thing.
