Make 'allAlpha' a special feature gate
Rather than making all caller check both allAlpha and their own flag, make `allAlpha` set all of the alpha gates explicitly.
This is hard to test because of the globalness. I will follow this commit with a new one to add some way to test, but I wanted to float this design

Currently if there is an error (not found) the error printed out
is to do with the inablity to convert an empty body into the expected json.
This patch will fill in the err correctly.
example of before (with NotFound error):
$ kubectl top node
failed to unmarshall heapster response: json: cannot unmarshal object into Go value of type []v1alpha1.NodeMetrics
Now:
$ kubectl top node
the server could not find the requested resource (get services http:heapster:)

remove duplicate code in updatePodCIDR
As kl.runtimeState.podCIDR() is a sync method, need fetch lock and release lock, so we only invoke once here
Kubernetes uses Docker labels as storage for some internal labels. The
majority of these labels are not meaningful metric labels and a few of
them are even harmful as they're not static and cause wrong aggregation
results.
This change provides a custom labels func to only attach meaningful
labels to cAdvisor exported metrics.

AWS: More ELB attributes via service annotations
Replaces #25015 and addresses all of @justinsb's feedback therein. This is a new PR because I was unable to reopen#25015 to amend it.
I noticed recently that there is existing (but undocumented) precedent for the AWS cloud provider to manage ELB-specifc load balancer configuration based on service annotations. In particular, one can _already_ designate an ELB as "internal" or enable PROXY protocol.
This PR extends this capability to the management of ELB attributes, which includes the following items:
* Access logs:
* Enabled / disabled
* Emit interval
* S3 bucket name
* S3 bucket prefix
* Connection draining:
* Enabled / disabled
* Timeout
* Connection:
* Idle timeout
* Cross-zone load balancing:
* Enabled / disabled
Some of these are possibly more useful than others. Use cases that immediately come to mind:
* Enabling cross-zone load balancing is potentially useful for "Ubernetes Light," or anyone otherwise attempting to spread worker nodes around multiple AZs.
* Increasing idle timeout is useful for the benefit of anyone dealing with long-running requests. An example I personally care about would be git pushes to Deis' builder component.
This patch includes the fix of the following issue:
• Correct the method invocation from "__kubectl_namespace_flag"
to "__kubectl_override_flags"
• Support bash completion if "--namespace=xxx" style flags are
specified in the kubectl command
Fixes#31134
