Avoid unnecessary copies on GCI initialization.
The issue I faced was that when starting a cluster I was getting:
```
Aug 12 11:12:46 e2e-test-wojtekt-master configure.sh[1079]: cp: error writing '/home/kubernetes/kubernetes-src.tar.gz': No space left on device
```
This PR reduces amount of space that is needed on startup, as well as this speeds up starting cluster.

Extend the wait time to 2*time.Minute for liveness check test.
Fixes https://github.com/kubernetes/kubernetes/issues/30264.
https://github.com/kubernetes/kubernetes/pull/29814 changes the wait time to 1 minute, which is not enough. That's what causes the flake.
The test expected the container to be restarted, and the container was indeed restarted but it took about 1 minute:

Add zsh compatibility note `completion` cmd help
zsh completions are not supported on zsh versions < 5.2.
This patch advices user on supported versions of zsh when using the `completion`
command to avoid potential UX failure.
##### After
`$ kubectl completion -h`
```
Output shell completion code for the given shell (bash or zsh).
This command prints shell code which must be evaluation to provide interactive
completion of kubectl commands.
Examples:
$ source <(kubectl completion bash)
will load the kubectl completion code for bash. Note that this depends on the
bash-completion framework. It must be sourced before sourcing the kubectl
completion, e.g. on the Mac:
$ brew install bash-completion
$ source $(brew --prefix)/etc/bash_completion
$ source <(kubectl completion bash)
If you use zsh*, the following will load kubectl zsh completion:
$ source <(kubectl completion zsh)
* zsh completions are only supported in versions of zsh >= 5.2
```

Add support for kube-up.sh to deploy Calico network policy to GCI masters
Also remove requirement for calicoctl from Debian / salt installed nodes and clean it up a little by deploying calico-node with a manifest rather than calicoctl. This also makes it more reliable by retrying properly.
How to use:
```
make quick-release
NETWORK_POLICY_PROVIDER=calico cluster/kube-up.sh
```
One place where I was uncertain:
- CPU allocations (on the master particularly, where there's very little spare capacity). I took some from etcd, but if there's a better way to decide this, I'm happy to change it.

Basic audit log
Fixes#2203 by introducing simple audit logging, including the information about impersonation. We currently have something identical in openshift, but I'm open to any suggestions. Sample logs look like that:
as `<self>`:

AUDIT: id="75114bb5-970a-47d5-a5f1-1e99cea0574c" response=200
```
as user:
```
AUDIT: id="b0a443ae-f7d8-408c-a355-eb9501fd5c59" ip="192.168.121.118" method="GET" user="system:admin" as="test-admin" namespace="openshift" uri="/api/v1/namespaces/openshift/pods/python"

Fix code generators-- make scheme building composable
I needed to make some changes to make my other refactoring possible and this got rather large.
We now provide a "SchemeBuilder" to help all of the api packages provide their scheme-building functions (addKnownTypes and friends) in a standardized way. This also allows generated deepcopies & conversions to be entirely self contained, the project will now build without them being present (as they can add themselves to the SchemeBuilder). (Although if you actually build without them, you will get reduced performance!)
Previously, there was no way to construct your own runtime.Scheme (e.g., to test), you had to use the api.Scheme object, which has all sorts of non-hermetic cruft in it. Now you can get everything from a package by calling the scheme builder's AddToScheme, including the generated functions, if they are present.
Next steps are to allow for declaring dependencies, and to standardize the registration & install code. (#25434)

the observed usage should match those that have hard constraints
in the sync process, the quota will be replenished, the new observed usage will be sumed from each evaluator, if the previousUsed set is not be cleared, the new usage will be dirty, maybe some unusage resource still in , as the code below
newUsage = quota.Mask(newUsage, matchedResources)
for key, value := range newUsage {
usage.Status.Used[key] = value
}
so i think here shoul not set value previousUsed

Quota admission errors if usage is negative
If quota observes negative usage for an artifact, that artifact could game the quota system.
This adds a global check in the quota system to catch this scenario for all evaluators.

This removes the need to manually specify the version in all but unusual
cases.
For most installs this will effectively flip the default from
v1 (deprecated) to v2 so conservative existing installs may want to
manually configure "lb-version = v1" before upgrading.
