Merge pull request #37649 from smarterclayton/top_node

Automatic merge from submit-queue

kubectl top pod|node should handle when Heapster is somewhere else

OpenShift runs Heapster on HTTPS, which means `top node` and `top pod`
are broken because they hardcode 'http' as the scheme. Provide an
options struct allowing users to specify `--heapster-namespace`,
`--heapster-service`, `--heapster-scheme`, and `--heapster-port` to the
commands (leveraging the existing defaults).

@kubernetes/sig-metrics makes top a little more useful in other spots
