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.

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.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#67091
**Special notes for your reviewer**:
**Release note**:
```release-note
cluster/gce: generate consistent key sizes in config-default.sh using /dev/urandom instead of /dev/random
```

Adding GCE node termination handler as an optional addon.
This step is a pre-requisite for auto-deploying that addon in GKE

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.
```
