Add Calico as policy provider in GCE
Adds Calico as policy provider to GCE, enforcing the extensions/v1beta1 NetworkPolicy API.
Still to do:
- [x] Enable NetworkPolicy API when POLICY_PROVIDER is provided.
- [x] Fix CNI plugin, policy controller versions.
CC @thockin - does this general approach look good?

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.

GCE provider: Limit Filter calls to regexps rather than insane blobs
Filters can't exceed 4k, and GET requests against the GCE API are also limited, so these break down in different ways at different cluster counts. Fix it by introducing an advisory `node-instance-prefix` configuration in the GCE provider that can hint the `EnsureLoadBalancer`/`UpdateLoadBalancer code` (and the firewall creation/update code). If it's not there, or wrong (a hostname that's registered violates it), just ignore it and grab the whole project.

federation: Creating kubeconfig files to be used for creating secrets for clusters on aws and gke
Extension of https://github.com/kubernetes/kubernetes/pull/26914 which created the kubeconfig files for gce clusters.
This PR extends it to AWS, vagrant and GKE.
The change for AWS and vagrant is exactly same as GCE.
For GKE, since `gcloud create clusters` creates kubeconfig, we are just copying the generated kubeconfig to the desired location

rkt: Map kubelet's `--stage1-image` flag to rkt's `--stage1-name` flag.
This enables rkt to use cached stage1 image instead of unpacking the stage1 image every time for every pod.
After this change, users need to preload the stage1 images in order to enable rkt to find the stage1 image with the name specified by this flag.
Also, the cloud config is modified to pre-load the stage1 images.

add logrotate service and configuration for GCI
This change mirrors the configuration in cluster/saltbase/salt/logrotate for GCI.
On GCI we use systemd timers (https://www.freedesktop.org/software/systemd/man/systemd.timer.html) and install an hourly timer - kube-logrotate.timer. This will invoke kube-logrotate.service (which calls /usr/sbin/logrotate) once every hour to perform log rotation as per the rotation rules installed under /etc/logrotate.d/.

Prep for continuous Docker validation test
```release-note
Add a test config variable to specify desired Docker version to run on GCI.
```
We want to continuously validate Docker releases (#25215), on GCI. This change
adds a new test config variable, `KUBE_GCI_DOCKER_VERSION`, through which we can
specify which version of Docker we want to run on the master and nodes. This
change also patches the Jenkins e2e-runner with the ability to fetch the latest
Docker (pre)release, and sets the aforementioned variable accordingly.
Tested on my local Jenkins instance that was able to start a cluster with the latest Docker version (different from installed version) running on both master and nodes.
@dchen1107 Can you review?

Revert "Revert "GCI: add support for network plugin""
PR #27027 added the network plugin support in GCI config, but later a bug in the network plugin broke e2e tests (see issue #27118). The bug was fixed by #27141 and we have been repeatedly run the serial e2e tests more than 10 times to verify the fix. Now it should be safe to put the GCI network plugin support back.
We will first merge in the master branch and monitor the Jenkins serial tests for a while and then cherry-pick it into release-1.3 branch.
