Add RetryOnConflict in order to fix
"the object has been modified; please apply your changes to the latest version and try again."
which can be caused by a legitimate k8s node update operation,
and require a reconcile retry.

Its important to add it also to the AfterEach,
else a conflict there might break the cluster
for the rests of the tests.
