Automatic merge from submit-queue (batch tested with PRs 42973, 41582) Improve status manager unit testing This is designed to simplify testing logic in the status manager, and decrease reliance on syncBatch. This is a smaller portion of #37119, and should be easier to review than that change. It makes the following changes: - creates convenience functions for get, update, and delete core.Action - prefers using syncPod on elements in the podStatusChannel to using syncBatch to reduce unintended reliance on syncBatch - combines consuming, validating, and clearing actions into single verifyActions function. This replaces calls to testSyncBatch(), verifyActions(), and ClearActions - changes comments in testing functions into log statements for easier debugging @Random-Liu
