http.wait_for_successful_query behaviour with `wait_for` and `request_interval`

Description of Issue

If request_interval is a large value, it can extend the wait time well beyond wait_for.

#51045 is similar issue with excessive waiting

Steps to Reproduce Issue

salt-call -l trace --local http.wait_for_successful_query wait_for=2 request_interval=100 http://127.0.0.1:5999

There is nothing on port 5999, so the request times out, but we end up waiting request_interval

Versions Report

This affects the master branch code.

This does not affect any release version for salt, as they do not have request_interval and will instead spam requests as fast as possible until wait_for. That was fixed #53738

Start by running the provided salt-call reproduction, then inspect the implementation of http.wait_for_successful_query and the handling of wait_for and request_interval. Confirm the current timing behavior and identify existing tests around this entry point. Done means a large request_interval cannot extend the total wait beyond wait_for, with the behavior covered by a regression test.
