Yu-Ju Hong 15e9760bd4 Kubelet: support retrieving stats using UID of mirror pod 
Kubelet supports retrieving stats for pods/containers with and without UID.
This does not always work for the static pods because users may get the UIDs of
the mirror pods from the API server, and use them to query Kubelet. In this
case, Kubelet would fail to locate the containers due to mismatched UIDs.

This change adds a intenral mirror to static pod UID mapping and teaches all
public-facing functions to perform UID lookup before proceeding. This allows
users to use either mirror or static pod's UID to retrieve stats.

Clayton Coleman 015bc3b7bd Remove global map from healthz 
It currently is impossible to use two healthz handlers on different
ports in the same process.  This removes the global variables in favor
of requiring the consumer to specify all health checks up front.

Jerzy Szczepkowski 5845f6ad48 Running resource predicate on kubelet. 
Added checking on kubelet if scheduled pods do not exceed resources. Related to #5207.

Yu-Ju Hong 929fb63b33 Sync static pods from Kubelet to the API server 
Currently, API server is not aware of the static pods (manifests from
sources other than the API server, e.g. file and http) at all. This is
inconvenient since users cannot check the static pods through kubectl.
It is also sub-optimal because scheduler is unaware of the resource
consumption by these static pods on the node.

This change syncs the information back to the API server by creating a
mirror pod via API server for each static pod.

 - Kubelet creates containers for the static pod, as it would do
   normally.

 - If a mirror pod gets deleted, Kubelet will re-create one. The
   containers are sync'd to the static pods, so they will not be
   affected.

 - If a static pod gets removed from the source (e.g. manifest file
   removed from the directory), the orphaned mirror pod will be deleted.

Note that because events are associated with UID, and the mirror pod has
a different UID than the original static pod, the events will not be
shown for the mirror pod when running `kubectl describe pod
<mirror_pod>`.
