upgrade us to HTTP/2 first.

federation-controller/clustercontroller: fix race when updating data
Fix#49958
Updates for ClusterController's maps were made without locking which can lead
to race conditions.
This change adds a RWMutex to protect the data. We lock and unlock them
whenever the data is accessed to make sure that we dont slow down too much

create default storage selection functions
The vast majority of our REST storage needs either default selection predicates or minor tweaks the the field selection criteria. This pull makes that work without any special fields set, but also allows the more complex configuration where it is required. I only changed one storage an example. Once this merges, I'll update the others.

Adding IPv6 to cidr_set and cidr_set_test
**What this PR does / why we need it**:
This allows IPv6 in cidr_set
Currently cidr_set only supports IPv4. This adds IPv6 compatibility and adds
IPv6 unit tests.

**Special notes for your reviewer**:
The IPv6 code here makes some assumptions.
The subnets should be at least /64. (maximum 64 bits of prefix)
The subnet mask size cannot be greater than 30 more than the cluster mask size.

Do not try to run preStopHook when the gracePeriod is 0
**What this PR does / why we need it**:
1. Sometimes when the user force deletes a POD with no gracePeriod, its possible that kubelet attempts to execute the preStopHook which will certainly fail. This PR prevents this inavitable PreStopHook failure.
```
kubectl delete --force --grace-period=0 po/<pod-name>
```
2. This also adds UT for LifeCycle Hooks
```
time go test --cover -v --run "Hook" ./pkg/kubelet/kuberuntime/

[Bug Fix] Fix updating LastHeartbeatTime for the OutOfDisk node condition.
Fixes#50058. #49841 for some (currently unknown) reason did not correctly update LastHeartbeatTime, causing OutOfDisk to be marked unknown.
I have not found the reason for this yet. This change makes the setNodeOODCondition method nearly identical to the other conditions (e.g. [setNodeMemoryPressureCondition](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/kubelet_node_status.go#L741)).
I have started a cluster with this change, and all nodes have been reporting `Ready` for 25 minutes.
