APIv4-Based Smart(er) Groups

This project will allow smart groups to be built from APIv4 criteria. The MVP would include a button in the API Explorer to save an api4 query as a smart group. This will also connect with the new Search Builder UI when that project is complete.

Tasks:

Allow swappable backend to smart groups
Extend smart group schema to store api4 query parameters
Add support for saving smart groups to API explorer UI.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
