missed enabling the API group by default. This rectifies that.
**Release note**:
```release-note
The autoscaling/v2beta1 API group is now enabled by default.

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`.

Recreate pod sandbox when the sandbox does not have an IP address.
**What this PR does / why we need it**:
Attempts to fix a bug where Pods do not receive networking when the kubelet restarts during pod creation.

If user specify floating-network-id, a floatingip be assigned to
LoadBalancer service, So its status contains a floatingip, but
GetLoadBalancer() only return vip.
WaitForAttach failed consistently with this error:
Heuristic determination of mount point failed:stat
/var/lib/kubelet/plugins/kubernetes.io/fc/<wwn>-lun-0:
no such file or directory
We should create dir first to avoid the error.
Fixes: #52674
If the user has provided the floating-ip options, then it's safe
to assume they want (only) the floating-ip to be the ingress IP;
if they have not provided floating-ip options, then the LB IP is
the only relevant value.
Fix#52566
This PR makes following changes.
- Simplify volume tearDown path for iSCSI and FC using
util.UnmountPath().
- Log lastErr during iscsi connection
If iscsid fails to connect second portal, currently
the error is ignored silently. The lastErr should be
logged to find the root cause of problem.
- Remove iscsi plugin directory after iscsi connection
is successfully closed.

Default http.ProxyFromEnvironment uses uppper case proxy
environment variables first, and if they are not defined,
tries lower case. For NewProxierWithNoProxyCIDR we should
provide similar user experience.
This commit will remove variables `zeroDuration`, `defaultNodeAllocatableEnforcement` and
constants `defaultIPTablesMasqueradeBit` and `defaultIPTablesDropBit` as they are unused.
Currently when evictSandboxes() checks whether sandbox contains
containers, it traverses all the containers for every sandbox,
but when cluster has many containres, it wastes a lot of time.
It is better to use sets in this case.

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.

The following changes are proposed for the iptables proxier:
* There are three places where a string specifying IP:port is parsed
using something like this:
if index := strings.Index(e.endpoint, ":"); index != -1 {
This will fail for IPv6 since V6 addresses contain colons. Also,
the V6 address is expected to be surrounded by square brackets
(i.e. []:). Fix this by replacing call to Index with
call to LastIndex() and stripping out square brackets.
* The String() method for the localPort struct should put square brackets
around IPv6 addresses.
* The logging in the merge() method for proxyServiceMap should put brackets
around IPv6 addresses.
* There are several places where filterRules destination is hardcoded to
/32. This should be a /128 for IPv6 case.
* Add IPv6 unit test cases

Changes the node cloud controller to use its name for events
**What this PR does / why we need it**:
