✨ Add experimental, feature-gated direct bundle install support

[joelanford]

Description

This PR adds experimental API and feature-gated functionality to support direct bundle installs, which avoid the need to dereference from a ClusterCatalog.

@perdasilva mentioned he put up #2252, and it reminded me that I had a commit like that in my really old shift-week PR from last year. This PR is mainly a rebase of that one commit, just for reference purposes.

@perdasilva feel free to do as you please with this PR! Ignore it, merge it, beg/borrow/steal from it, or anything in between!
