Support running generate-groups.sh from any directory, so users can run
it from their own projects, instead of forcing them to run it from here.
This allows the generators to find and use go source code from a
project's vendor directory, for example.

When kubeadm upgrades a static pod cluster, the old manifests were previously
deleted. This patch alters this behaviour so they are now stored in a
timestamped temporary directory.

kubeadm: conditionally set the kubelet cgroup driver for Docker
**What this PR does / why we need it**:
Add a new utility file - util/cgroupdriver.go.
Currently it only contains the public function GetCgroupDriverDocker().
The function uses 'docker info' to obtain the cgroup driver
for Docker.
On a later stage this file can contain more methods for different
CRI.
Use GetCgroupDriverDocker() in phases/kubelet/flags.go
to conditionally set the 'cgroup-driver' argument. On error
print a warning and don't set the argument value.
Add unit tests in cgroupdriver_test.go.

Add KUBE_CGO_OVERRIDES env var to force enabling CGO
**What this PR does / why we need it**: as detailed in https://github.com/kubernetes/release/issues/469 (and elsewhere), there is a desire to have `kubectl` built with CGO enabled on mac OS.
There currently isn't a great way to do this in our official cross builds, but we should allow mac users to build their own kubectl with CGO enabled if they desire, e.g. through homebrew.
This change enables that; you can now do `KUBE_CGO_OVERRIDES=kubectl make WHAT=cmd/kubectl` and get a cgo-enabled `kubectl`.
The default build outputs remain unchanged.
**Release note**:
```release-note
kubectl built for darwin from darwin now enables cgo to use the system-native C libraries for DNS resolution. Cross-compiled kubectl (e.g. from an official kubernetes release) still uses the go-native netgo DNS implementation.

Possible cipher suites values and tls versions in help for apiserver and kubelet
**What this PR does / why we need it**:
Addresses a suggestion made by @lavalamp to list the possible TLS cipher suites in the kubelet and apiserver helps: https://github.com/kubernetes/kubernetes/pull/48859#discussion_r162413223
**Which issue(s) this PR fixes**
NONE
**Special notes for your reviewer**:
This pull request only adds to the help message the possible values of the TLS Cipher suites for Kubelet and api server.
It is an addition to the already merged PR https://github.com/kubernetes/kubernetes/pull/48859
The help output looks like this:
```
--tls-cert-file string File containing the default x509 Certificate for HTTPS. (CA cert, if any, concatenated after server cert). If HTTPS serving is enabled, and --tls-cert-file and --tls-private-key-file are not provided, a self-signed certificate and key are generated for the public address and saved to the directory specified by --cert-dir.
--tls-cipher-suites strings Comma-separated list of cipher suites for the server. Values are from tls package constants (https://golang.org/pkg/crypto/tls/#pkg-constants). If omitted, the default Go cipher suites will be use. Possible values: TLS_ECDHE_ECDSA_WITH_RC4_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_RSA_WITH_3DES_EDE_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_RC4_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
--tls-min-version string Minimum TLS version supported. Value must match version names from https://golang.org/pkg/crypto/tls/#pkg-constants.
--tls-private-key-file string File containing the default x509 private key matching --tls-cert-file.

Use default seccomp profile for flutend-elasticsearch addons
**What this PR does / why we need it**:
This PR sets the default seccomp profile to 'docker/default' for:
- fluentd-es daemon set.
- kibana-logging deployment.
The elasticsearch-logging stateful set is still unconfined because it uses gce:podsecuritypolicy:privileged.
This PR is a followup of #62662. We are using 'docker/default' instead of 'runtime/default' in addons in order to handle node version skew. When seccomp profile is applied automatically by default later, we can remove those annotations.
This is PR is part of #39845.
