Prevent a Kubelet from shutting down when the server isn't responding to
us but we cannot get a new certificate. This allows a cluster to coast
if the master is unresponsive or a node is partitioned and their client
cert expires.
Clients shouldn't have to know about watch.ErrWatchClosed, which is
typically a server side decision to close and always means "Timeout" in
this conetxt.
The client cert manager uses the most recent cert to request new
certificates. If that certificate is expired, it will be unable to
complete new CSR requests. This commit alters the manager to force
process exit if no further client cert rotation is possible, which
is expected to trigger a restart of the kubelet and either a
re-bootstrap from the bootstrap kubeconfig or a re-read of the
current disk state (assuming that some other agent is managing the
bootstrap configuration).
This prevents the Kubelet from wedging in a state where it cannot make
API calls.
Ensures that in a crash loop state we can make forward progress by
generating a new key and hence new CSR. If we do not delete the key, an
expired CSR may block startup.
Also more aggressively delete a bad cert path
Before the bootstrap client is used, check a number of conditions that
ensure it can be safely loaded by the server. If any of those conditions
are invalid, re-bootstrap the node. This is primarily to force
bootstrapping without human intervention when a certificate is expired,
but also handles partial file corruption.

Update rules_go, repo-infra, and rules_docker dependencies
**What this PR does / why we need it**: several of our bazel dependencies were getting pretty old, since they required bazel 0.5.4+ but there were various failures if we tried to use them with bazel 0.5.4.
Now that bazel 0.6.0 (and 0.6.1) have been out for a while, we can bump our dependencies and get a number of fixes and new functionality.
x-ref #52677 and others
**Special notes for your reviewer**:
* This will now explicitly require bazel 0.6.0+ to build kubernetes.
* Our staging directories are causing some issues for `gazelle`; it wants to set `importpath = "k8s.io/kubernetes/staging/src/k8s.io/blah"` instead of `importpath = "k8s.io/blah"`. I'm not sure what is the correct way to fix this; what we're doing here is pretty weird and nonstandard. I've used a `sed` substitution for now.
* The `-proto=default` option of `gazelle` has a number of bugs right now (https://github.com/bazelbuild/rules_go/issues/888, https://github.com/bazelbuild/rules_go/issues/900, https://github.com/bazelbuild/rules_go/issues/907), so I am forcing the legacy behavior.

remove redundant error test case in autoscaling validation
Signed-off-by: allencloud <allen.sun@daocloud.io>
**What this PR does / why we need it**:
I think the error test case I removed is the same as https://github.com/kubernetes/kubernetes/blob/master/pkg/apis/autoscaling/validation/validation_test.go#L393-L412 .
So maybe removal of this part is proper, since it would reduce the codes and save a little bit time in testing.

improve kubectl cp command in several ways
**Release note**:
"kubectl cp" process soft link in better ways as well as some little bugs
**Soft link**:
before this patch
"kubectl cp" command will copy the soft link to destination as an empty regular file
after this patch
"kubectl cp" command will behave the same as tar command
this patch improves it on both from container and to container
**some bugs**
1.from container to host
a.when copy a file ends with '/', it will cause a panic.
for example, container gakki has a regular file /tmp/test, then run command
_kubectl cp gakki:/tmp/test/ /tmp_
a panic happens
b.when copy a file which does not exist in container, the command ends up without
any error information
2.from host to container
a.when run command like
kubectl cp "" gakki:/tmp
it will try cp current directory to container, in other words, this command works
the same as kubectl cp . gakki:/tmp
b.current cp command will omit an empty directory
