Default kube-proxy to the old behavior for proxier sync.
Fix#36281.
This PR defaults `minSyncPeriod` to 0 and makes kube-proxy fall back to the old behavior to fix the immediate problem #36266.

Fix a data race condition in federation namespace controller
Fixes https://github.com/kubernetes/kubernetes/issues/36364
Fixing federation namespace controller to create a copy of namespace fetched from the store before editing it. Without it there is a data race condition with other readers of the store.

The e2e tests cover cases like cluster size changed, parameters
changed, ConfigMap got deleted, autoscaler pod got deleted, etc.
They are separated into a fast part(could be run parallelly) and
a slow part(put in [serial]). The fast part of the e2e tests cost
around 50 seconds to run.

Add verify script for federation OpenAPI spec generation
We are missing hack/verify-federation-openapi-spec.sh. It should be something similar to hack/verify-openapi-spec.sh.

Rename ScheduledJobs to CronJobs
I went with @smarterclayton idea of registering named types in schema. This way we can support both the new (CronJobs) and old (ScheduledJobs) resource name. Fixes#32150.

Not ready yet, but getting close there...
**Release note**:
```release-note
Rename ScheduledJobs to CronJobs.

Update fluentd-gcp configuration
Related to #32762
Though it's not a final solution to the fluentd OOM problems, it increases number of logs that can be handled without losses by
- switching to the file buffering, making buffering mechanism more resilient
- decreasing size of the buffer, decreasing the amount of memory needed
- decreasing number of threads handling the load, since number of chunks is lower than previous number of threads
which results in decrease in theoretical throughput. Tests to confirm cases covered by this change will follow.
cc @piosz @edsiper @repeatedly please take look and confirm that all of these changed are meaningful.

Fix hack/local-up by declaring defaults for unbound env vars
The variables were not defaulted and caused hack/local-up-cluster to not work.
This allows us to interrupt/kill the executed command if it exceeds the
timeout (not implemented by this commit).
Set timeout in Exec probes. HTTPGet and TCPSocket probes respect the
timeout, while Exec probes used to ignore it.
Add e2e test for exec probe with timeout. However, the test is skipped
while the default exec handler doesn't support timeouts.
struct hostPathPlugin contains newRecyclerFunc, newDeleterFunc and newProvisionerFunc items that have only one instance, i.e. newRecycler, newDeleter or newProvisioner function.
That's why the newRecyclerFunc, newDeleterFunc and newProvisionerFunc items are removed and the newRecycler, newDeleter or newProvisioner functions are called directly.
In addition, the TestRecycler tests whether NewFakeRecycler function is called and returns nil. This is no longer needed so this particular part of the test is removed. In addition, the no longer used NewFakeRecycler function is removed also.
Similarly for the NFS plugin, struct nfsPlugin contains newRecyclerFunc item that has only one instance, i.e. newRecycler function. That's why the newRecyclerFunc item is removed and the newRecycler function is called directly. In addition, the TestRecycler tests whether newMockRecycler function is called and returns nil. This is no longer needed so this particular part of the test is removed. In addition, the no longer used newMockRecycler function is removed also.

azure: loadbalancer rules use DSR
**What this PR does / why we need it**:
Enables "direct server return" on the load balancer in Azure, which causes the DIP to be preserved when traffic goes through the load balancer. This enables service traffic to go to the Service Port rather than having to go through the NodePort.
**Special notes for your reviewer**:
N/A.
**Tested with...**:
```shell
kubectl run nginx --image=nginx
kubectl run nginx2 --image=nginx
kubectl expose deployment nginx --port=80 --type=LoadBalancer
kubectl expose deployment nginx2 --port=80 --type=LoadBalancer
```
Ensuring that both services got external IPs and that the resources created looked correct.
**Release note**:
```release-note
azure: load balancer preserves destination ip address
```

Adding more e2e tests for federated namespace cascading deletion and fixing bugs
Ref https://github.com/kubernetes/kubernetes/issues/33612
Adding more e2e tests for testing cascading deletion of federated namespace.
New tests are now verifying that cascading deletion happen when DeletionOptions.OrphanDependents=false and it does not happen when DeleteOptions.OrphanDependents=true.
Also updated deletion helper to always add OrphanFinalizer. generic registry will remove it if DeleteOptions.OrphanDependents=false. Also updated namespace registry to do the same.
We need to add the orphan finalizer to keep the orphan by default behavior. We assume that its dependents are going to be orphaned and hence add that finalizer. If user does not want the orphan behavior, he can do so using DeleteOptions and then the registry will remove that finalizer.
