Today rollout operator determines to continue the release when other statefulset replications' pods are ready/running required for write quorum.
However it is possible some statefulsets were running hot and had OOM kills recently. This PR will block rollout if and only if other replications detect recent OOM Kills. This will make release safer in an already hot cluster while not blocking current statefulset.
Added multiple unit tests.
