Precalculate authorized projects in database
What does this MR do?
It caches user's authorized projects in database instead of using multiple unions, which should simplify and speed-up things since this operation (getting authorized projects) is used a lot.
Are there points in the code the reviewer needs to double check?
Did we miss a scenario where we need to refresh the list of projects?
