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.

Support journal logs in fluentd-gcp on GCI
This maintains a single common image for each rather than having to fork out separate images, relying on different commands in yaml manifests to differentiate in the behavior. This is treading on top of @adityakali's #27906, but I wasn't able to get in touch with him this afternoon until very recently. He's handling making sure that the new yaml manifests are used when running on GCI.

kubenet: Fix host port for rktnetes.
Because rkt pod runs after plugin.SetUpPod() is called, so
getRunningPods() does not return the newly created pod, which
causes the hostport iptable rules to be missing for this new pod.

Only run the systemd-journal plugin when on a platform that requests it.
The plugin crashes the fluentd process if the journal isn't present, so
it can't just be run blindly in all configurations.

This service seems broken, probably because the k8s repo is larger than
the normal project. I have emailed the service author but for the time
being remove the badge.
Because rkt pod runs after plugin.SetUpPod() is called, so
getRunningPods() does not return the newly created pod, which
causes the hostport iptable rules to be missing for this new pod.

Add support for Docker for MacOS
With Docker for MacOS [public beta](https://docs.docker.com/docker-for-mac) you don't need docker-machine on MacOS to build kubernetes instead you can use docker "natively". Per Default Docker for MacOS will be installed to `/Applications/Docker.app/Contents/MacOS/Docker` so if Docker for Mac is installed we should use the native version.
I tested it locally with `15.5.0 Darwin Kernel Version 15.5.0` and Docker version `1.12.0-rc2`

Adding SCSI controller type filter for vSphere disk attach
Hot plug of disks to a SCSI controller of type lsilogic doesn't work as expected. When a device is detached from the controller, it fails to remove the device from the /dev path which makes the subsequent attaches to the node to fail. With scsi controller types lsilogic-sas or paravirtual this seems to work well. This patch filters the existing controller for these types, and if it doesn't find one, it creates a new controller for disk attach.
This PR is dependent on https://github.com/kubernetes/kubernetes/pull/26658 (1st commit) also targeting this for 1.3
