The watch for CRD getting ready used wrong error when checking if it is retriable. This results in bogus logging and a "busyloop":

time="2024-05-16 10:05:45" level=info msg="Transient error while watching etcdmember CRD, last observed version is \"\", starting over after 0s ..." component=etcdMemberReconciler error="<nil>"
time="2024-05-16 10:05:45" level=info msg="Transient error while watching etcdmember CRD, last observed version is \"\", starting over after 0s ..." component=etcdMemberReconciler error="<nil>"
time="2024-05-16 10:05:45" level=info msg="Transient error while watching etcdmember CRD, last observed version is \"\", starting over after 0s ..." component=etcdMemberReconciler error="<nil>"
...

It actually hides the transient errors encountered.
