reconcile: Add support for progressive status

Replace the patch Helper with SerialPatcher which is used for
progressive status patching.

Update the tests to use progressive status reasons in tests.

Add ProgressingWithRetry Reconciling reason for failed
reconciliation result to indicate a finished failure operation.
