This change includes the yaml files and gce startup script changes
to run this addon. It is disabled by default, can be enabled by setting
KUBE_ENABLE_NODELOCAL_DNS=true
An ip address is required for the cache instance to listen for
requests on, default is a link local ip address of value 169.254.25.10
addressed review comments, updated image location
Picked a different prometheus port so stats port is not same as the
coredns deployment
Removed the nodelocaldns-ready label.
Set memory limit to 30Mi
2. Do not set Preemptible node label on master node unless the master node is explicitly set to be preemptible.

Remove e2e-image-puller
**What this PR does / why we need it**:
A long time ago, We added the image prepulling as a workaround due to
the overwhelming amount of flake caused by pulling during the tests.
This functionality has been broken for a while now when we switched to a
COS image where mounting `docker` binary into `busybox` stopped working.
So we just have dead code we should clean up.

Fix an issue about generation of secret key with invalid key size in gce
Replace /dev/random to /dev/urandom to avoid generation of secret key with invalid key size.
**What this PR does / why we need it**:
In GCE env, AESGCM encryption of secrets by default generates a secret key with /dev/random which sometime generates a key with invalid size.
This cause the cluster/kube-up.sh to fail in gce environment.
This PR replaces /dev/random with /dev/urandom to have a secret key generated consistently with right size.

In the context, our urandoms where generally safe, however getrandom has
built in invariants around entropy pool initialization, making getrandom
safe in all contexts. This should protect us from cryptopasta errors or
weird entropy issues.

Support extra prune resources in kube-addon-manager.
The default prune whitelist resources in https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/apply.go#L531 are sometimes not enough.
One example is that when we remove an admission webhook running as an addon pod, after we remove the addon yaml file, the admission webhook pod will be pruned, but the `MutatingWebhookConfiguration`/`ValidationWebhookConfiguration` won't... If the webhook failure policy is `Fail`, this will break the cluster, and users can't create new pods anymore.
It would be good to at least make this configurable, so that users and vendors can configure it based on their requirement.
This PR keeps the default prune resource list exactly the same with before, just makes it possible to add extra ones.

Enable CoreDNS as default for kube-up deployments
**What this PR does / why we need it**:
Enable CoreDNS as default (for kube-up installations)
It will allow to run CI tests to prepare graduation criteria for CoreDNS as Default
see : KEP - https://github.com/kubernetes/community/blob/master/keps/sig-network/0012-20180518-coredns-default-proposal.md
see also : https://github.com/kubernetes/features/issues/566
NOTE for release : I guess that CoreDNS as default server for k8s needs a longer description. This specific PR is to ensure we validate all e2e.
```release-note
Make CoreDNS be the default DNS server in kube-up (instead of kube-dns formerly).
It is still possible to deploy kube-dns by setting CLUSTER_DNS_CORE_DNS=false.

The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.
SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.
SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter
changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.
netexec.go compilation fixed. Various test cases fixed
SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)
SCTP related e2e test cases are removed as the e2e test systems do not support SCTP
sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go
cluster/gce/util.sh is copied from master
Implemented the call to get all cluster objects in a zone for a project.
Also added code to allow the container api to be set in the gce.conf
file.
Requested fix for @lavalamp. Fixed GetClusters to be GetManagedClusters.
Leaving ListClusters as ListClusters as it is part of the Cloud Clusters
interface, despite also being a "managed" call.
Remove copy pasta :D
