Updaing QoS policy to be at the pod level
Quality of Service will be derived from an entire Pod Spec, instead of being derived from resource specifications of individual resources per-container.
A Pod is `Guaranteed` iff all its containers have limits == requests for all the first-class resources (cpu, memory as of now).
A Pod is `BestEffort` iff requests & limits are not specified for any resource across all containers.
A Pod is `Burstable` otherwise.
Note: Existing pods might be more susceptible to OOM Kills on the node due to this PR! To protect pods from being OOM killed on the node, set `limits` for all resources across all containers in a pod.

systemd node spec proposal
The following outlines changes that I want to make to the ```kubelet``` in order to better integrate with ```systemd``` systems, and to better isolate containers in their own ```cgroup``` based on the qos tier.
I think this is a precursor to getting more intelligent low compute resource eviction.

Kubelet pod eviction proposal
The following is a proposal for how the `kubelet` may pro-actively fail a pod in response to local compute resources being starved. The proposal focuses on memory as a first candidate, and defines a `greedy` strategy for reclaiming starved resources on the node since it seemed easiest to describe for operators versus other options and probably satisfies a broad set of use case environments.
Putting this out now for community feedback, but anticipate some more refinement around how we report eviction configuration back to users in the `Node API`.

Add proposal for kubelet TLS bootstrap
A proposal based on the discussion of issue #18112, to implement a process by which kubelets can obtain TLS certificates in a streamlined manner.

Proposal for improving local cluster experience.
This proposal attempts to improve the existing single node, local cluster experience in Kubernetes.
It is **not** a proposal that helps with setting up a multi-node, production cluster.
