controller-manager in k8sm:
- rename host_port_endpoints flag to host-port-endpoints
- host port mapping strategy in scheduler should be driven by host-port-endpoints flag
- added host-port-endpoints to known flags
- docs: scheduler should also be configured with host-port-endpoints
- task recovery: be explicit about excluding mirror pods
We know there are some flags (declared with an _) which we wish to
ignore. These flags are used by container definitions, e2e, etc. By
explicitly ignoring those flags we can cut the amount of noise in the
whitelist.
