kubectl explain ingress.spec.rules.http.paths. is valid
and defaults to kubectl explain ingress.spec.rules.http.paths
Rational: We use kubectl explain by adding fields
(e.g. service, then service.spec, then service.spec.ports ...)
so it's very easy to forget a trailing . at the end. We should
ignore the trailing period and display the result without it.

hyperkube: add cloud-controller-manager
**What this PR does / why we need it**:
Adds `cloud-controller-manager` to `hyperkube`. (fix#55732)
This is useful as a number of deployment tools run all of the kubernetes components from the `hyperkube` image/binary. It also makes testing easier as a single binary/image can be built and pushed quickly.
This PR follows the same pattern of the other kubernetes binaries being available as part of `hyperkube`.
(This PR also makes an error condition appropriately fatal.)

Fix prometheus-to-sd sidecar in metadata proxy
Ref https://github.com/kubernetes/kubernetes/issues/55695#issuecomment-344300188
This is making 2 changes:
- restoring resource requests and limits of the metadata-proxy sidecar as it was before, and remove them for prom-to-sd sidecar (best effort) like at everywhere else
- pass pod name and namespace args to prom-to-sd sidecar (because just noticed)
/cc @ihmccreery @loburm @crassirostris - Does this make sense?
