47d3299781 node: metrics: cpumanager: add pinning metrics 
In order to improve the observability of the cpumanager,
add and populate metrics to track if the combination of
the kubelet configuration and podspec would trigger
exclusive core allocation and pinning.

We should avoid leaking any node/machine specific information
(e.g. core ids, even though this is admittedly an extreme example);
tracking these metrics seems to be a good first step, because
it allows us to get feedback without exposing details.

ba6b468982 node: metrics: register podresources metrics 
Because of a bug in the commit 1e7bb20c52,
podresources metrics were added, they are updated in the right
places, but they are never exported, so they cannot be consumed.
Fix trivially registering the metrics.

kubelet: Record a metric for latency of pod status update 
Track how long it takes for pod updates to propagate from detection
to successful change on API server. Will guide future improvements
in pod start and shutdown latency.

Metric is `kubelet_pod_status_sync_duration_seconds` and is ALPHA
stability. Histogram buckets are chosen based on distribution of
observed status delays in practice.

1e7bb20c52 kubelet: podresources: per-endpoint metrics 
Before the addition of GetAllocatableResources, the
podresources API had just one endpoint `List()`, thus we could just
account for the total of the calls to have a good pulse of the API usage.
Now that we extend the API with more endpoints
(`GetAlloctableResources`), in order to improve the observability we add
per-endpoint counters, in addition to the existing counter of the total
API calls.

Allow debugging kubelet image pull times 
This PR changes the buckets of the
kubelet_runtime_operation_duration_seconds metric to be
metrics.ExponentialBuckets(.005, 2.5, 14) in order to
allow debugging image pull times. Right now the biggest bucket is 10
seconds, which is an ordinary time frame to pull an image, making the
metric useless for the aforementioned usecase.
