Making DHCP_OPTION_SET_ID creation optional
Reason: We have a pre-configured VPC in AWS. `kube-up.sh` should not making changes to the VPC DHCP option if there's already DHCP options configured.
PR Changes: When `DHCP_OPTION_SET_ID` is given in environment variable, kube-up.sh will skip the `DHCP_OPTION_SET_ID` creation.

Enable setting up Kubernetes cluster in Ubuntu on Azure
Implement basic cloud provider functionality to deploy Kubernetes on
Azure. SaltStack is used to deploy Kubernetes on top of Ubuntu
virtual machines. OpenVpn provides network connectivity. For
kubelet authentication, we use basic authentication (username and
password). The scripts use the legacy Azure Service Management APIs.
We have set up a nightly test job in our Jenkins server for federated
testing to run the e2e test suite on Azure. With the cloud provider
scripts in this commit, 14 e2e test cases pass in this environment.
We plan to implement additional Azure functionality to support more
test cases.

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?

Tracked addition of federation, sed support in kube DNS
[]()
The kube DNS app recently gained support for federation (whatever that
is), including a new Salt parameter. This broke the deployAddons.sh script for cluster ubuntu. The DNS app also gained alternate
templates, intended to be friendly to `sed`. Fortunately, those do
not demand a federation parameter.
This PR fixes up the ` cluster/ubuntu/deployAddons.sh` script to track those changes, by switching to the `sed`-friendly templates.

mount instanceid file from config drive when using openstack cloud provider
fix https://github.com/kubernetes/kubernetes/issues/23191, the instanceid file is read however we do not mount it as a volume, and it would cause the cloud provider contacts the metadata server, in some cases, the metadata server is not able to serve, then the cloud provider would fail to initialize, we should avoid that.

cluster/aws: Add option for kubeconfig context

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.
```release-note
```
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.

AWS kube-up: Authorize route53 in the IAM policy
Federation needs this now (on the nodes), and I suspect ingress

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/.

Update to dnsmasq:1.3 and make hyperkube always use the latest addons
This bumps dnsmasq to a version that works on all architectures: https://github.com/kubernetes/contrib/pull/1192 (which have to be pushed first indeed)
Also I removed the manifests in hyperkube addons in favor for machine-generated ones, which will avoid mistakes.
This one is required for `v1.3`, so it has to be cherrypicked I think...
It makes docker and docker-multinode addons work again...
(Yes, we'll probably get rid of docker in favor for minikube, but we'll have to have it in this release at least)
