**What this PR does / why we need it**:

Currently, we use `glog.Infof` to print the log when proxy-mode is unknown, I think we may need to modify to `glog.Warningf`.

**Which issue this PR fixes**: 

fixes #31405

Remove implicit Prometheus metrics from client

**What this PR does / why we need it**: This PR starts to cut away at dependencies that the client has.

**Release note**:
<!--  Steps to write your release note:
1. Use the release-note-* labels to set the release note state (if you have access) 
2. Enter your extended release note in the below block; leaving it blank means using the PR title as the release note. If no release note is required, just write `NONE`. 
-->
```release-note
The implicit registration of Prometheus metrics for request count and latency have been removed, and a plug-able interface was added. If you were using our client libraries in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/client/metrics/prometheus".

Add flags to control max connections (set to 256k vs 64k default) and TCP

mean "don't change it".

This is only set at startup, and not wrapped in a rectifier loop.

Tested manually.

Default to hardcodes for components that had them, and 5.0 qps, 10 burst

Unclear if maybe it'd be better to just assume these are set as part of
the incoming kubeconfig.  For now just exposing them as flags since it's
easier for me to manually tweak.

Tim Hockin bd3cd82a12 Change kube-proxy flag: annotation for proxy-mode
This changes the --legacy-userspace-proxy flag to be a string flag
--proxy-mode.  If specified, the flag will be respected ('userspace' and
'iptables' being valid values).  If left blank (default) we will choose the
"best".  best means userspace for now UNLESS the user adds an annotation
(net.experimental.kubernetes.io/proxy-mode) to their node, in which case we
will try to use that.

This allows people to try it on a single machine without fear of global failure
and without it getting rolled back on reboots.  It is a poor-man's config blob.

Check to make sure there is not an alphanumeric character immeditely

this is obviously not actually the flag we care about.  For example if
the project declares a flag "valid-name" but the regex finds something
like "invalid_name" we should not match.  Clearly this "invalid_name" is
not actually a wrong usage of the "valid-name" flag.
