Allow namespace to be loaded from in-cluster config
This is a follow on from the previous commit that fixed ClientConfig.
Namespace can also be defaulted from ICC, and this correctly handles
that logic. Also add two debugging lines to ensure that it is easier in
the future to uncover problems here.
Fixes#32352

Revert "Merge pull request #30513 from tmrts/kubelet-rkt-cri/use-imag…
This reverts commit aff7dfcaab, reversing
changes made to 7a4d81ea43.
See https://github.com/kubernetes/kubernetes/pull/30513#issuecomment-245949664, this breaks tests for the rkt runtime.
The original PR also changed the source of image truth from the api-service to cli, which could have further implications which @yifan-gu could speak better to, so I think it's safer to just revert for now and discuss further in the rktlet repo / pr. The reverted code effectively already exists (with the bug in question already fixed) here https://github.com/kubernetes-incubator/rktlet/pull/5 .. once that's merged, we can vendor and call it over here in place of #30513.
@yifan-gu / @tmrts if you think continuing with the changes and rolling forwards (just adding the `--full` flag to list to fix the immediate bug) is better, feel free to close this and open a PR with that change, but I think this approach is overall better for the reasons in the previous paragraph.

Revert "e2e: only tear down existing cluster if it exists"
Reverts kubernetes/kubernetes#32420
This broke more things. We're going to backport the `|| true` fix to 1.2 -- doing just enough maintenance on old branches to keep upgrades working with new infra changes.

Add node e2e density test using 60 QPS for benchmark
This PR adds a new benchmark node e2e density test which sets Kubelet API QPS limit from default 5 to 60, through ConfigMap.
The latency caused by API QPS limit is as large as ~30% when creating a large batch of pods (e.g. 105). It makes the pod startup latency, as well creation throughput underestimated. This test helps us to know the real performance of Kubelet core.

Namespace Controller handles items with finalizers gracefully
This PR does the following:
1. ensures the "orphan" finalizer is not added to items during DELETE COLLECTION calls
2. does not treat presence of a finalizer as an unexpected error condition.
The 15s wait should only happen when finalizers not added by GC are used.
I am aware of any finalizer like that at this time.

update error handling for daemoncontroller
Updates the DaemonSet controller to cleanly requeue with ratelimiting on errors, make use of the `utilruntime.HandleError` consistently, and wait for preconditions before doing work.
@ncdc @liggitt @sttts My plan is to use this one as an example of how to handle requeuing, preconditions, and processing error handling.
