@houdini91 I have not forgotten about this PR. I just added it to our internal board now so I'll start working on getting you a review as soon as I can carve out some time.

Just a quick update - it looks like @wagoodman has pulled in the configuration cataloger work under joint issue #1039 with the PR via #1038.

@houdini91 I'm going to close this PR since we have another PR that hooks into the new API proposed in #558 (#1383). The new PR lacks some features from this PR (such as cataloger groups) but this PR would essentially need to be rewritten based on the upcoming changes.

If you're still interested in some of these features please feel free to reach out and I'd be happy to work with you!
