Updates Kubeadm Master Endpoint for IPv6
**What this PR does / why we need it**:
Previously, kubeadm would use ip:port to construct a master
endpoint. This works fine for IPv4 addresses, but not for IPv6.
Per [RFC 3986](https://www.ietf.org/rfc/rfc3986.txt), IPv6 requires the ip to be encased in brackets
when being joined to a port with a colon.
This patch updates kubeadm to support wrapping a v6 address with
[] to form the master endpoint url. Since this functionality is
needed in multiple areas, a dedicated util function was created
for this purpose.
**Which issue this PR fixes**
Fixes Issue https://github.com/kubernetes/kubeadm/issues/334
**Special notes for your reviewer**:
As part of a bigger effort to add IPv6 support to Kubernetes:

What this PR does / why we need it:
This adds an e2e test for aggregation based on the sample-apiserver.
Currently is uses a sample-apiserver built as of 1.7.
This should ensure that the aggregation system works end-to-end.
It will also help detect if we break "old" extension api servers.

Fixed bazel for the change.
Fixed # of args issue from govet.
Added code to test dynamic.Client.
Copy of previous newrelic example, then modified to use the new agent
"newrelic-infra" instead of "nrsysmond".
Also maps all of host node's root fs into /host in the container (ro,
but still exposes underlying node info into a container).

kubeadm: Fix self-hosting race condition
**What this PR does / why we need it**:
Splitted out from: https://github.com/kubernetes/kubernetes/pull/50766
Waits for the Static Pod to be deleted before proceeding with checking the API health.
Otherwise there is a race condition where we're checking the health on the static pod API server; not the self-hosted one that we expect.
Also improves the logging output and adds reasonable timeouts for the process

p.s. looks like the `Set()` method could be removed if the value is accepted as an argument to `New()`. I.e. looks like to code re-sets the value.

Make endpoints controller update based on semantic equality
Fixes#50828
Split from https://github.com/kubernetes/kubernetes/pull/45294 for separate review
Currently, endpoints objects containing no subsets are decoded by the go client as subsets:[] (when requested individually) or as subsets:null (when requested in a list of endpoints).
Because the endpoints controller is fed via a lister/watcher, it gets the `subsets:null` version fed to it. The subsets computation then returns an empty slice, which fails reflect.DeepEqual, which triggers a write attempt.
This PR makes the comparison use semantic.DeepEqual to avoid spurious writes.
https://github.com/kubernetes/kubernetes/pull/45294 would remove the inconsistency between lists and individual gets.

**What this PR does / why we need it**: `kazel` shouldn't be looking under skipped paths (like `_output`) for openapi files. This was fixed in https://github.com/kubernetes/repo-infra/pull/32 and now should be included here.
I've tested locally that this now ignores everything under `_output`.

Make socket address parsing work on FreeBSD.
**What this PR does / why we need it**:
I am currently in the process of porting Kubernetes to work on FreeBSD. What is interesting is that I am not interested in using Kubernetes to run Docker containers in this case. I happen to be the author of CloudABI, a sandboxing framework that is available on FreeBSD (and other systems). I want to have a cluster management tool for scheduling these sandboxed processes.
Anyway, right now `kubelet` crashes on startup when passing in CRI command line flags, for the reason that it's not able to parse `unix:...` socket addresses. This change fixes this by making the respective Linux-only source file work on FreeBSD as well.

Add ReclaimPolicy field to StorageClass
fix https://github.com/kubernetes/kubernetes/issues/38192, enough people want this imo so going ahead and adding it according to initial suggested design
some considerations:
* No Recycle allowed, Retain (& Delete) only.
* Do we need to gate the field.
* E2E test where a Retain PV is dynamically provisioned is TODO if we agree we want this & this is the way to do it.
* Need a feature repo issue to track docs and stuff for 1.8
**Release note**:
```release-note
StorageClass has a new field to configure reclaim policy of dynamically provisioned PVs.
