Kube-proxy runs two different health servers; one for monitoring the
health of kube-proxy itself, and one for monitoring the health of
specific services. Rename them to "ProxierHealthServer" and
"ServiceHealthServer" to make this clearer, and do a bit of API
cleanup too.
This should fix a bug that could break masters when the EndpointSlice
feature gate was enabled. This was all tied to how the apiserver creates
and manages it's own services and endpoints (or in this case endpoint
slices). Consumers of endpoint slices also need to know about the
corresponding service. Previously we were trying to set an owner
reference here for this purpose, but that came with potential downsides
and increased complexity. This commit changes behavior of the apiserver
endpointslice integration to set the service name label instead of owner
references, and simplifies consumer logic to reference that (both are
set by the EndpointSlice controller).
Additionally, this should fix a bug with the EndpointSlice GenerateName
value that had previously been set with a "." as a suffix.
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Remove ExternalTrafficLocalOnly from kube_feature gate
*What this PR does / why we need it**:
This PR is for v1.10.
External Source IP Preservation (ESIPP) had been promoted to GA since 1.7. Following the proposal on https://github.com/kubernetes/kubernetes/issues/46404#issuecomment-303939180, we should be able to remove it from feature gate now.
Added release note to announce this.
Also ref the previous attempt: https://github.com/kubernetes/kubernetes/pull/45857.

**Release note**:
```release-note
"ExternalTrafficLocalOnly" has been removed from feature gate. It has been a GA feature since v1.7.

Implement dummy device operation by netlink for ipvs proxier
**What this PR does / why we need it**:
Currently, we implement network interface operations, e.g. create a dummy device and delete a dummy interface via ip cmd and then collect the exist code. For example, we assume the following command:
```
ip link add kube-ipvs0 type dummy
```
returns 2 means the dummy device `kube-ipvs0` exists, see https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/ipvs/proxier.go#L1529 .
However, from the man page of ip command, exit status 2 just means an error was reported by the kernel, see http://man7.org/linux/man-pages/man8/ip.8.html#EXIT_STATUS.
So, that's a bug.
This PR implements dummy device operation by netlink for ipvs proxier so that can get ride of ip command operations.

bazel: build/test almost everything
**What this PR does / why we need it**: Miscellaneous cleanups and bug fixes. The main motivating idea here was to make `bazel build //...` and `bazel test //...` mostly work. (There's a few reasons these still don't work, but we're a lot closer.)

**Release note**:
