add delete-namespace-on-failure flag
I have been doing this for a while.
Setting `--delete-namespace=false --clean-start=true` only works if you have only one e2e test running in a loop.
This PR lets someone to set `delete-namespace-on-failure=false` and run multiple tests in parallel and preserve the crime scene. It makes it easier to reproduce failures.
Let me know if this is worth it or there are some other tricks I am not aware.

Delete federation namespace after the test completes
The code was commented because of a bug in namespace deletion which is now fixed.
Note that this deletes the namespace in federation control plane. We still need to delete the namespace from each cluster (cascading deletion)

Add a retry loop to KubeletManagerEtcHosts flake
Add a retry loop to KubeletManagerEtcHosts flake
Note: this still makes the test fail if a retry occurs, but
will give us more information regarding whether or not the
test flake could be occuring due to delay in mounting of
/etc/hosts.

Check for empty string post trimming
We curl in a retry loop and timeout, trimming stdout to find endpoint names. When curl hits the timeout, stdout is empty, so we insert the empty string into the received set of endpoints.

[Client-gen] Let versioned client use versioned options
i.e., use v1.ListOptions, v1.DeleteOptions when possible.
Remove the extension/v1beta1.ListOptions, because it's exactly the same as v1.ListOptions, and is not referred throughout the code base. After its removal, I register v1.ListOptions during extensions/v1beta1 scheme registration.
First three commits are manual changes.
Fix#27753

Fix kubelet perf data to make it work again for perfdash.
Addresses https://github.com/kubernetes/kubernetes/pull/30333#issuecomment-248791257.
Add the "node" label back to fix kubelet perf dash. At least for now, we still need original perfdash to catch summary api performance regression.

Heal the namespaceless ingresses in federation e2e.
For createIngressOrFail, it incorrectly returned the ingress passed in as an argument, which does not include the namespace, instead of the ingress returned from the create call (which does).
This in turn leads to errors in e2e tests like this:
INFO: Waiting for Ingress federated-ingress to acquire IP, error an empty namespace may not be set when a resource name is provided.
Self-applying LGTM label, as this is the same code that was LGTM'd by @nikhiljindal in #33502

Delete evicted pet
If pet was evicted by kubelet - it will stuck in this state forever.
By analogy to regular pod we need to re-create pet so that it will
be re-scheduled to another node, so in order to re-create pet
and preserve consitent naming we will delete it in petset controller
and create after that.

fix kubectl taint e2e flake: add retries for removing taint
**What this PR does / why we need it**:
Why we need it: recent failures occurred in #29503 are caused by taints removing conflict on nodes, this PR is to fix it. (#33073 fixed taints updating conflict, but not taints removing.)
What this PR does: use `runKubectlRetryOrDie()` instead of `RunKubectlOrDie()` in all the places in "Kubectl taint" e2e tests.
**Which issue this PR fixes** : fixes part of #29503, (would like to keep this issue open for some days more to make sure no other failures occur)
**Special notes for your reviewer**: NONE
**Release note**: NONE
