Default ABAC to off in GCE (for new clusters).
**What this PR does / why we need it**:
Disables the legacy ABAC authorizer by default on GCE/GKE clusters using kube-up.sh. Existing clusters upgrading to 1.8 will keep their existing configuration.
**Release note**:
```release-note
New GCE or GKE clusters created with `cluster/kube-up.sh` will not enable the legacy ABAC authorizer by default. If you would like to enable the legacy ABAC authorizer, export ENABLE_LEGACY_ABAC=true before running `cluster/kube-up.sh`.

Add bootstrap policy for HPA metrics REST clients
Since we weren't running the HPA with metrics REST clients by default,
we had no bootstrap policy enabling the HPA controller to talk to the
metrics APIs.
This adds permissions for the HPA controller to talk list
pods.metrics.k8s.io, and list any resource in custom.metrics.k8s.io.
```release-note
Introduce policy to allow the HPA to consume the metrics.k8s.io and custom.metrics.k8s.io API groups.

Eliminate hangs/throttling of node heartbeat
Fixes https://github.com/kubernetes/kubernetes/issues/48638Fixes#50304
Stops kubelet from wedging when updating node status if unable to establish tcp connection.
Notes that this only affects the node status loop. The pod sync loop would still hang until the dead TCP connections timed out, so more work is needed to keep the sync loop responsive in the face of network issues, but this change lets existing pods coast without the node controller trying to evict them
```release-note
kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs

Add cluster-name option for cloud controller manager
**What this PR does / why we need it**:
`cluster-name` is used by servicecontroller and routecontroller, for controller-manager, we have a parameter to set it, but for cloud-controller-manager, it will always be of default value 'kubernetes'.
An example of impact is Azure's loadbalancer, the loadbalancer resource created will always have the name 'kubernetes', while it used to be the cluster name set via controller manger's option.

Changes the node cloud controller to use its name for events
**What this PR does / why we need it**:
Updates the event recorder component to be the `cloud-node-controller` instead of `cloudcontrollermanager`, which aligns with how other controllers are setup like the daemonset controller which uses `daemonset-controller` and the ccm uses `cloud-controller-manager`.
