Explore alternative methods for unpacking catalog data

[everettraven]

Following #65 it is probably a good idea to explore what alternatives exist for unpacking methods separate from copying implementations from rukpak.

Some potential alternatives:

• Make catalogd a rukpak provisioner
• Make the rukpak unpacking implementation a library

There's also concerns from @ncdc about the fidelity of pod logs being read by the controller (specifically, logs being complete, and therefore being a reliable source of complete content). Instead the suggestion is that unpack jobs/pods should send the data back to catalogd using a service endpoint:port that catalogd makes available for these uploads, and the logs are then stored reliably in the filesystem/create confimap/s with the data, before they're consumed

Should this be turned into a discussion?
