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

Dynamically determine default docker machine memory
**What this PR does / why we need it**:
Currently, if using `docker-machine` for k8s docker operations on a Mac,
we'll create a VM with 4096MB of memory. The machine's RAM will be the
same regardless of the memory available on the local machine. For
example, if the user has 16GB on their local machine, the VM will still
only have 4GB of RAM.
Update the method for defining the `kube-dev` VM with `docker-machine`,
so we give it access to 50% of the total RAM.

Create new targets for running in existing containers (GCB).
1. release-in-a-container - Like 'make release' but in a container.
2. cross-in-a-container - Like 'make cross' but in a container.
3. package-tarballs - (NEW) To package tarballs with a docker dependency
'release-in-a-container' is currently only for testing and is not slated to
be used, but may be useful for testing in some scenarios.
'cross-in-a-container' is meant to be run from the kube-cross image alone.
'package-tarballs' is a companion target that runs from a docker image
to package up the tarballs and images (from cross-in-a-container) for a release.
This is an early step to being able to build releases in Container Builder.

Adding e2e tests to verify vsphere volume lifecycle on a clustered datastore
**What this PR does / why we need it**:
This PR introduces tests for volume provisioning on a clustered datastore. It does so in three ways
1. Static provisioning (create vsphere volume and then create a pod with it)
2. Dynamic provisioning (specify clustered datastore in storage class parameters)
3. Dynamic provisioning with spbm policy (specify storage policy name in storage class parameters. This policy is a tag based policy and tagged to a clustered datastore)
**Which issue this PR fixes** :
fixes vmware#278

Kubelet Evictions take Priority into account
Issue: https://github.com/kubernetes/kubernetes/issues/22212
This implements the eviction strategy documented here: https://github.com/kubernetes/community/pull/1162, and discussed here: https://github.com/kubernetes/community/pull/846.
When priority is not enabled, all pods are treated as equal priority.
This PR makes the following changes:
1. Changes the eviction ordering strategy to (usage < requests, priority, usage - requests)
2. Changes unit testing to account for this change in eviction strategy (including tests where priority is disabled).
3. Adds a node e2e test which tests the eviction ordering of pods with different priorities.
