NewInstallerProfileRejectionChecker is used to construct a CheckProfileRejectionFunc that can compare the (installer controller generated config map) config of the latest active revision with the desired/target latency profile to return whether profile transition should be rejected or not.

NewInstallerRevisionConfigMatcher is used to create a MatchProfileRevisionConfigsFunc that can be matches config maps generated by installer controller for various static pod revisions and match if each of the active revisions specified contain arg val pairs specific to given latency profile or not.

LatencyProfileController either instantly via the informers or periodically via resync, lists the config/v1/node object and fetches the worker latency profile applied on the cluster which is used to updates the status of respective operator resource that uses this controller.
