Network camera with HTTP

Describe the issue/problem and steps to reproduce

Using motion on RPi 3 combined with network camera (HTTP serving a JPG image for every request). I don't need motion detection or stream saving - only taking image snapshots in regular intervals of 60 seconds. Looks like somewhere between version 4.2.2 and 4.5.1 some logic has changed and motion no longer allows a "quiet" mode in which the HTTP requests would be fired off only when needed (or simply looking at the value of minimum_frame_time 30). Version 4.5.1 requests the updates at the minimal rate of 1 image per second which is way beyond my need.

It would be great if the old behaviour could be brought back as it would really help me to tame CPU time on my Raspberry Pi.
