906286c743 Change order kubelet starts containers 
This starts ephemeral containers prior to init containers so that
ephemeral containers will still be started when init containers fail to
start.

Also improves tests and comments with review suggestions.

2bdf975d5b kubelet: add UID to kubelet_container_log_filesystem_used_bytes metric 
buildPodRef creates a unique key with the {podName, namespace, UID}
tuple. By omitting the UID in the metric, duplicate metrics can be sent
to prometheus causing 500's on the /metrics endpoint.

c6d9bbcb74 Proactively remove init Containers in CPUManager static policy 
This patch fixes a bug in the CPUManager, whereby it doesn't honor the
"effective requests/limits" of a Pod as defined by:

    https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#resources

The rule states that a Pod’s "effective request/limit" for a resource
should be the larger of:
    * The highest of any particular resource request or limit
      defined on all init Containers
    * The sum of all app Containers request/limit for a
      resource

Moreover, the rule states that:
    * The effective QoS tier is the same for init Containers
      and app containers alike

This means that the resource requests of init Containers and app
Containers should be able to overlap, such that the larger of the two
becomes the "effective resource request/limit" for the Pod. Likewise,
if a QoS tier of "Guaranteed" is determined for the Pod, then both init
Containers and app Containers should run in this tier.

In its current implementation, the CPU manager honors the effective QoS
tier for both init and app containers, but doesn't honor the "effective
request/limit" correctly.

Instead, it treats the "effective request/limit" as:
    * The sum of all init Containers plus the sum of all app
      Containers request/limit for a resource

It does this by not proactively removing the CPUs given to previous init
containers when new containers are being created. In the worst case,
this causes the CPUManager to give non-overlapping CPUs to all
containers (whether init or app) in the "Guaranteed" QoS tier before any
of the containers in the Pod actually start.

This effectively blocks these Pods from running if the total number of
CPUs being requested across init and app Containers goes beyond the
limits of the system.

This patch fixes this problem by updating the CPUManager static policy
so that it proactively removes any guaranteed CPUs it has granted to
init Containers before allocating CPUs to app containers. Since all init
container are run sequentially, it also makes sure this proactive
removal happens for previous init containers when allocating CPUs to
later ones.
