ac88cd7691 helpers: refactor and expose function for sum of container req/limits
Currently we only care about the sum of sandbox resources, which
includes a pod overhead if defined. We have a need for also calculating
*just* the sum of container requests/limits for CPU / Memory, so let's
do a refactor and expose this new helper function.

scheduler: Implement resource metrics at /metrics/resources
Implement pod resource metrics as described in KEP 1916. The new
`/metrics/resources` endpoint is exposed on the active scheduler
and reports kube_pod_resources* metrics that present the effective
requests and limits for all resources on the pods as calculated by
the scheduler and kubelet. This allows administrators using the
system to quickly perform resource consumption, reservation, and
pending utilization calculations when those metrics are read.
Because metrics calculation is on-demand, there is no additional
resource consumption incurred by the scheduler unless the endpoint
is scraped.

991909fdfb PodOverhead: remove feature gate override in tests
PodOverhead is now a beta feature and set to true by default. No need to
override to true during testing.

80ee072b85 pod-overhead: utilize pod overhead for cgroup sizing, eviction handling
Pod and burstable QoS cgroups should take overhead of running a sandbox
into account if the PodOverhead feature is enabled. These helper
functions are utilized by Kubelet for sizing the pod and burstable QoS
cgroups.

Pod overhead is added to resource requests, regardless of the initial
request values. A particular resource pod overhead is only added to a
resource limit if a non-zero limit already existed.

This commit updates eviction handling to also take Pod Overhead into
account (if the feature is enabled).

9d2d37be27 resource: modify resource helpers for better reuse
Update GetResoureqRequest function to utilize a new helper,
GetResourceRequestQuantity. This logic was duplicated in a couple of
areas in the K/K codebase, so consolidating for better test coverage.
