Abstraction of endpoints in leaderelection code
**Problem Statement**:
Currently the Leader Election code is hard coded against the endpoints api. This causes performance issues on large scale clusters due to incessant iptables refreshes, see: https://github.com/kubernetes/kubernetes/issues/26637
The goal of this PR is to:
- Abstract Endpoints out of the leader election code
- Fix a known bug in the event recording
fixes#18386
**Special notes for your reviewer**:
This is a 1st pass at abstracting the details of endpoints out into an interface. Any suggestions around how we we want to refactor this interface is welcome and could be addressed in either this PR or follow on PR.

Node-ip is not used when cloud provider is used
Currently --node-ip in kubelet is not being used when kubelet is configured with a cloud provider. With this fix, kubelet will get a list of IPs from the provider and parse it to return the one that matches node-ip.
This fixes#23568

Bump glbc version to 0.8.0
Picks up k8s.io godeps for v1.4 thereby fixing an int overflow bug in the upstream delayed-workqueue pkg. Without this the controller spams logs with retries in the "soft error" case, which is easy to come by when users eg: create ingresses that point to non-exist services.
Should go into 1.4.1, because 1.4.0 is pretty much out at this point.

add optional env var for allowing version skew in test cmd
If you only make a change to a server component and then re-run `test-cmd` you get a skew error. This is really annoying. I've left the default as it was (force version match), but now also allow `ALLOW_SKEW=true hack/test-cmd.sh` to skip the check.
@eparis worth a quick bash check, but I think I got it.

Use patched golang1.7.1 for cross-builds targeting darwin
This PR extends #32517 to use the patched go1.7.1 introduced by that PR to build all darwin targets (e.g. kubectl).
This is necessary because binaries built with earlier versions of Go regularly segfault on macOS Sierra (see #32999 and #33070).
This solution is somewhat hacky, but we intend to cherry-pick this to 1.4, and switching all of 1.4 to build with go1.7.1 is very high risk.
I haven't yet pushed the cross build image yet, so this will fail to build. Will test locally and update with results.
First step of fixing #33801.

Add community expectations about conduct and reviewing.
@sarahnovotny @smarterclayton @philips @thockin @davidopp @jbeda
As discussed in the previous community meeting here's a description of the expectations around community, I expanded it a little bit beyond code review because it seemed like a good place to put it
down in one location.
Please let me know what I got wrong (or right ;)
Thanks
