tests: Replace common integration sleeps with polling

Browse Source 
Use polling helpers in common integration tests instead of fixed
sleeps where the tests already know the expected ready state.

This updates CPU and memory hotplug checks as well as a few
device- and restore-related waits in common_parallel to stop
oversleeping on the fast path while keeping the same assertions.
