return nil from NewClientConfig instead of empty struct
This is a go convention and fixes an nil pointer in kubelet when passing in bad command line options:

Adding lock files for kubeconfig updating
This is to prevent concurrent executions from corrupting the kubeconfig file.
Also, release note?

to remove workflow proposal
@erictune @brendanburns
I think workflow proposal should be removed now. If you have a specific plan to remove it disregard this.

Build Darwin test binaries on OS X when KUBE_FASTBUILD is set
Without this, on OS X, test binaries would not be built for the local ARCH, and test scripts fail with an obscure error due to not being able to find the correct binary to run.
This makes the behavior on OS X more consistent with Linux.
Tested on OS X and Linux.

Fixed an error in lvm bash script
The space in this script is an obvious typo and caused an error

e2e: Delete old code
These tests were added commented out over a year ago. Now they don't compile. The port forward test has a whole file devoted to replacing it (`e2e/portforward.go`) and while the exec test doesn't have a perfect replacement, it has several tests that cover for it (exec over a websocket, an e2e_node test, all the kubectl execs). If we want that test, it would be better to write it fresh anyways.

cluster/aws: Add option for kubeconfig context
Added KUBE_CONFIG_CONTEXT environment variable to customize the kubeconfig context created at the end of the aws kube-up script.
Fixes#24877
This PR does barely anything and shouldn't require e2e tests. It's just a minor convenience.

Add retries on 429s & 5xxs to the Auth webhooks
This gets some retry logic above the restclient (as proposed in https://github.com/kubernetes/kubernetes/issues/27965#issuecomment-228188192).
I'd like to add a unit test, but I'm not coming with a good way without either gross stubbing or making a few fields in restclient.Result public. Any thoughts?

Workardound KubeProxy failures in test framework
Ref https://github.com/kubernetes/kubernetes/issues/25543
This is obviously not a fix - this is just test-framework-related workaround to avoid situations when we spin up a 2000-node clusters for few hours and then are not even to run tests.

Use gcloud for default node pool and api for other in cluster autoscaler e2e test
cc: @piosz @jszczepkowski @fgrzadkowski
Currently there is a problem with gcloud when non-default pool is used for cluster update. So we temporarily switch to the old ca-enable method for non-default pools until it is fixed.

federation service controller: fixing the logic to update DNS records
dd78dd8e2b introduced an 'endpointsReachable' boolean argument to ensureDnsRrrsets(), which is incorrect.
The logic prior to the above commit does the right thing, provided that the correct set of healthy endpoints are passed into that function.
This PR essentially reverts the part of the above commit related to 'endpointsReachable', and adds some debug logging (at --v=4) in case it becomes necessary.

A few changes to federated-service e2e test.
Most of the changes that get the test to pass have been made already or
elsewhere. Here we restructure a bit fixing a nesting problem, extend the
timeouts, and start creating distinct backend pods that I'll delete in the
non-local test (coming shortly).
Also some extra debugging info in the DNS code. I made some upstream
changes to skydns in https://github.com/skynetservices/skydns/pull/283
For #27739
Includes a commit from @madhusudancs that I will remove once his merges.

federation: Updating KubeDNS to try finding a local service first for federation query
Ref https://github.com/kubernetes/kubernetes/issues/26762
Updating KubeDNS to try to find a local service first for federation query.
Without this change, KubeDNS always returns the DNS hostname, even if a local service exists.
Have updated the code to first remove federation name from path if it exists, so that the default search for local service happens. If we dont find a local service, then we try to find the DNS hostname.
Will appreciate a strong review since this is my first change to KubeDNS.
https://github.com/kubernetes/kubernetes/pull/25727 was the original PR that added federation support to KubeDNS.
