feat(playlists): implement playlist plugin

[kuangp]

Signed-off-by: Phil Kuang [email protected]

Hey, I just made a Pull Request!

(Apologies for the giant change here 😅)

I put together an implementation of my playlist idea from #6063 but generalized for all entities. Check out the READMEs and demo below for more details!

Potential Future Enhancements

• Clean up of stale entities refs (deleted entities that are still referenced by playlists)
• UI customization for integrators
• Playlist search collator / ResultListItem to add playlists to search
• More metadata to improve discoverability of useful playlists eg. tags?
• Pagination to support scaling
• Distributed edits / conflict resolution support (if we want to get fancy 😁)

Hey @kuangp sorry I was holding off reviewing this as had a few other bits going on, will get to it this week! :pray:

Just a quick pass right now, but I'm wondering about the naming of the plugin. playlist is a bit ambiguous. Not sure 🤷 @backstage/maintainers?

perhaps entity-playlist ?

@kuangp yep sorry, on my radar! It's a big one so needs a bigger chunk of time, which I haven't sliced out just yet 😅
