Description

For now, mirror all images and a main yum repo from a kickstart repo.

Design

Have the FirstStage of pulp_rpm try to download and parse the tree info file. From this file create the declarative content unit of the DistributionTree model (the actual content unit). Have the Stages API process this unit like any other.

When actually saving the DistributionTree content unit in the ContentUnitSaver stage, have any additional model creation happen then.

Syncing Sub Repos

Some entries in the kickstart tree identify a "sub repo". that's not an official term, but it's intended to mean another valid repodata folder that identifies another set of RPMs that is outside of the main /repodata/ folder. One main challenge is efficiently syncing these "sub repos".

One easy solution we came up with is to instantiate multiple RPMDeclarativeVersion instances, one for each sub-repo and one for the main repo. This allows each one to work out of a different repository. The trick is to not instantiate more than 1 at once that way rate limiting, etc won't be an issue.

What about remotes for sub Repos?

We should create an in-memory Remote for the sub-repos. It shouldn't modify the real Remote because we don't want to do that. Also it needs all the settings from the original remote, e.g. proxy settings, ssl, etc so all those should be copied. The one difference needs to be the url, it needs to be appended with the sub-path url of the sub-repo from the treeinfo file.
