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).

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.
