Improve fatal error description for init in genericapiserver.go
When api.NewRequestContextFilter return error in the "init" function of genericapiserver.go, there are no handler info, add more information to indicate s.Handler or s.InsecureHandler, I suggest.

Optimise the New function in genericapiserver.go
It needn't the handlerContainer variable in the "New" function when deal s.HandlerContainer, I think, and it seems the codes more concise.

[garbage collector] add e2e test
This PR also includes some changes to plumb controller-manager's `--enable_garbage_collector` from the environment variable.
The e2e test will not be run by the core suite because it's marked `[Feature:GarbageCollector]`.
The corresponding jenkins job configuration PR is https://github.com/kubernetes/test-infra/pull/132.

Fix watch cache filtering
When serving watch events for a particular namespace, the watch cache filters out events from other namespaces by checking the etcd key of the event's object, and making sure it is prefixed with the root key for the namespace being watched.
The prefix check does not ensure the match occurs on a path segment boundary, so a watch on namespace `test` is delivered watch events for namespace `test1`.
This tightens the check to ensure the prefix match occurs on a path segment boundary.

Support terminal resizing for exec/attach/run
```release-note
Add support for terminal resizing for exec, attach, and run. Note that for Docker, exec sessions
inherit the environment from the primary process, so if the container was created with tty=false,
that means the exec session's TERM variable will default to "dumb". Users can override this by
setting TERM=xterm (or whatever is appropriate) to get the correct "smart" terminal behavior.
```

genconversion=false should skip fields during conversion generation
Currently it only skips if the fields don't match, but that leaves no
way for callers to say "no really, ignore this field".
@wojtek-t @thockin *must* be able to ignore a non-convertible field (if the types are different but we still want the autogeneration of everything else)

Optimise the process of the CalculateSpreadPriority in selector_spreading.go
It had better inspect if the nodeLister is normal first in the CalculateSpreadPriority in selector_spreading.go. If the nodeLister.List return error, the function return directly, not need deal the serviceLister and controllerLister and replicaSetLister.

Don't panic if we hit a dangling symlink in mungedocs
I hit this because I have a dangling symlink, which would cause a panic.

Log restclient request/response bodies using %#v.
These are now protobufs, so outputting them with %s dumps a large
amount of binary garbage into the log. %#v properly escapes exotic
characters.

Retry when apiserver fails to listen on insecure port
The apiserver will already continually retry when it fails to bind to the secure port. However, with the insecure port it does not retry, and any failures cause the apiserver to exit.
This change makes it so the api-server will retry on both insecure/secure ports.
A use-case for this change is for self-hosting the api-server, particularly when you are only running a single copy in your cluster. In some bootstrap and upgrade scenarios - it's necessary to replace/pivot from an existing api-server on the same host -- where you need a new copy running before tearing down the old (which is problematic when the api-server will try to bind to an in-use port and exit).

update resource builder error message to be more clear
release-note-none
The error message given by command line `kubectl get` is sometimes of no help / not clear on what must be corrected, e.g.：
`kubectl get pod pod/database-1-i10b9`
error: when passing arguments in resource/name form, all arguments must include the resource
##### Steps to Reproduce:
1. Run command "$ kubectl get pod pod/database-1-i10b9"
##### Actual Result:
Get unfriendly error message which is of no help:
"error: when passing arguments in resource/name form, all arguments must include the resource"
##### Expected Result:
Error message should recommend end user to run this cli in good grammar: "$ kubectl get pod database-1-i10b9" or "$ kubectl get pod/database-1-i10b9"
##### Before
"error: when passing arguments in resource/name form, all arguments must include the resource"
##### After
"error: there is no need to specify a resource type as a separate argument when passing arguments in resource/name form (e.g. `kubectl get resource/<resource_name>` instead of `kubectl get resource resource/<resource_name>`"
