0b80c43f76 Set the oom_score_adj of guaranteed pod to -997 
When oom happens, the sandbox maybe killed first, so set the oom score of guaranteed pod to -997.

Refactor docker specific oom const out of qos pkg 
Previously, `pkg/kubelet/qos` contained two different docker-specific
OOM constants. One set the oom adj for sandbox docker containers and the
other set the oom adj for the docker daemon. Move both to be closer to
their actual usages in `dockershim`.

This change addresses a TODO and leads us towards the overall goal of
making `pkg/kubelet` runtime agnostic except for `dockershim`.

Set PodStatus QOSClass field

This PR continues the work for https://github.com/kubernetes/kubernetes/pull/37968

It converts all local usage of the `qos` package class types to the new API level types (first commit) and sets the pod status QOSClass field in the at pod creation time on the API server in `PrepareForCreate` and in the kubelet in the pod status update path (second commit).  This way the pod QOS class is set even if the pod isn't scheduled yet.

Fixes #33255

Docker daemon and kubelet needs to be protected by setting oom-score-adj to -999.
