Remove hacks added for mesos

Since Mesos is no longer in your main repository and since we have
things like dynamic kubelet configuration in progress, we should
drop these undocumented, untested, private hooks.

cmd/kubelet/app/server.go::CreateAPIServerClientConfig
CreateAPIServerClientConfig::getRuntime
pkg/kubelet/kubelet_pods.go::getPhase

Also remove stuff from Dependencies struct that were specific to
the Mesos integration (ContainerRuntimeOptions and Options)

Also remove stale references in test/e2e and and test owners file

test/e2e/framework/service_util.go
