Allow running kube-proxy as a DaemonSet when using kube-up.sh on GCE
**What this PR does / why we need it**:
From #23225, this PR adds an option for user to run kube-proxy as a DaemonSet instead of static pods using GCE startup scripts. By default, kube-proxy will run as static pods.
This is the first step for moving kube-proxy into a DaemonSet in GCE, remaining tasks will be tracked on #23225.
**Special notes for your reviewer**:
The last commit are purely for testing out kube-proxy as daemonset via CIs.

**Release note**:
```release-note
When using kube-up.sh on GCE, user could set env `KUBE_PROXY_DAEMONSET=true` to run kube-proxy as a DaemonSet. kube-proxy is run as static pods by default.

Replaces use of --api-servers with --kubeconfig in Kubelet args across

Reduce scheduler CPU request to 75m
On a 1 cpu master we are over budget with CPU requests. Components like npd or cluster autoscaler don't have *any* space to run. We need to reduce some requests.

NODE_TAINTS in gce startup scripts
Currently there is now way to pass a list of taints that should be added on node registration (at least not in gce or other saltbased deployment). This PR adds necessary plumbing to pass the taints from user or instance group template to kubelet startup flags.
```release-note
Taints support in gce/salt startup scripts.

The PR was manually tested.
```
NODE_TAINTS: 'dedicated=ml:NoSchedule'

```

Mark Static pods on the Master as critical
fixes#47277.
A known issue with static pods is that they do not interact well with evictions. If a static pod is evicted or oom killed, then it will never be recreated. To mitigate this, we do not evict static pods that are critical. In addition, non-critical pods are candidates for preemption if a critical pod is scheduled to the node. If there are not enough allocatable resources on the node, this causes the static pod to be preempted.
This PR marks all static pods in the kube-system namspace as critical.

Audit webhook config for GCE
Add a `ADVANCED_AUDIT_BACKEND` (comma delimited list) environment variable to the GCE cluster config to select the audit backend, and add configuration for the webhook backend.
~~Based on the first commit from https://github.com/kubernetes/kubernetes/pull/46557~~
For kubernetes/features#22
Since this is GCE-only configuration plumbing, I think this should be exempt from code-freeze.

Major Changelog:
Bug fix: adding backends to existing backend-services #652
Bug fix: handling of secret-based SSL Certs #639
Add second LB healthcheck/proxy traffic source CIDR #574#479
Support backside re-encryption (HTTPS) #519
```
The two noted bugs are common occurrences for GKE users
**Release note**:
```release-note
Bump GLBC version to 0.9.3
```
Use shared informers instead of creating local controllers/reflectors
for the proxy's endpoints and service configs. This allows downstream
integrators to pass in preexisting shared informers to save on memory &
cpu usage.
This also enables the cache mutation detector for kube-proxy for those
presubmit jobs that already turn it on.

Add an env KUBE_ENABLE_MASTER_NOSCHEDULE_TAINT and disable it by default
This PR changed master `NoSchedule` taint to opt-in.
As is discussed with @bgrant0607 @janetkuo, `NoSchedule` master taint breaks existing user workload, we should not enable it by default.
Previously, NPD required the taint because it can only support one OS distro with a specific configuration. If master and node are using different OS distros, NPD will not work either on master or node. However, we've already fixed this in https://github.com/kubernetes/kubernetes/pull/40206, so for NPD it's fine to disable the taint.
This should work, but I'll still try it in my cluster to confirm.

Re-add kube_proxy to the abac file (Match what we had in 1.5).
**What this PR does / why we need it**:
Make the ABAC file match what it was in 1.5. GKE rewrites the ABAC file every time, so we were clobbering the kube_proxy entry that used to exist. This would have gone unnoticed, but a separate bug in GKE is causing the token file rewrites to fail on GKE (meaning group used in RBAC aren't there).
