Is your feature request related to a problem? Please describe.
I observe that some endpoints time out at 30s and get a 504. I then observe the front-end immediately re-issuing those requests. A concrete example is trying to fetch privileges or maybe just table details on the database details page.

Describe the solution you'd like
The page out to back off up to some number of minutes between making the requests if it is going to re-issue them at all.

Describe alternatives you've considered
Don't retry and move into an error state.
