[katello-devel] Katello (Pulp) Distribution vs. Foreman OS

[Dmitri Dolguikh]

This is to figure out how the two entities relate to each other, and 
what sort of orchestration we'd need on the Katello side.

Distribution: defines family, variant, version, url, and arch attributes 
(plus a few more). All of these are supported by Pulp.
Operating System: keeps track of hosts, images, puppet classes, and 
config-templates among other things. Operating System is related to 
several Katello Distributions (differentiated by architecture).

Distribution will have to be extended to persist Operating System id 
locally.

Create/Delete operation on Distribution would require corresponding 
changes in Operating Systems:
  - on Distribution creation:
   - create Architecture in Foreman (only if doesn't already exist)
   - create Media in Foreman (only if there is no existing Media with 
the same path)
   - create the OS in Foreman
   - create Distribution in Pulp
   - persist Foreman OS id in Katello

  On Distribution Delete:
   - delete the OS in Foreman (I assume Foreman cleans up 
Architecture/Media as required)
   - delete Distribution in Pulp
   - remove OS id stored in Katello
