graduate DynamicKubeletConfig feature to beta
Everything in the https://github.com/kubernetes/features/issues/281 beta target except a few documentation-related items is complete. Docs should be done very soon, so I'm sending this PR to graduate to beta before freeze.
```release-note
The dynamic Kubelet config feature is now beta, and the DynamicKubeletConfig feature gate is on by default. In order to use dynamic Kubelet config, ensure that the Kubelet's --dynamic-config-dir option is set.

Dump Stack when docker fails on healthcheck
Save stack dump of docker daemon in order to be able to
investigate why docker daemon was unresposive to `docker ps`

Use 'docker/default' as default seccomp profile for unprivileged PodSecurityPolicy
**What this PR does / why we need it**:
This PR sets the default seccomp profile for unprivileged PodSecurityPolicy to 'docker/default'. This PR is a followup of [#62662](https://github.com/kubernetes/kubernetes/pull/62662). We are using 'docker/default' instead of 'runtime/default' in addons in order to handle node version skew. When default seccomp profile is applied later, we can remove those annotations.

gce: Prefer MASTER_ADVERTISE_ADDRESS in apiserver setup
MASTER_ADVERTISE_ADDRESS is used to set the --advertise-address flag
for the apiserver. It's useful for running the apiserver behind a load
balancer.
However, if PROJECT_ID, TOKEN_URL, TOKEN_BODY, and NODE_NETWORK are
all set, the GCE VM's external IP address will be fetched and used
instead and MASTER_ADVERTISE_ADDRESS will be ignored.
Change this behavior so that MASTER_ADVERTISE_ADDRESS takes precedence
because it's more specific. We still fall back to using the VM's
external IP address if the other variables are set.
Also: Move the setting of --ssh-user and --ssh-keyfile based on
PROXY_SSH_USER) to a top-level block because this is common to all
codepaths.

Install and use crictl in gce kube-up.sh
Download and use crictl in gce kube-up.sh.
This PR:
1. Downloads crictl `v1.0.0-beta.0` onto the node, which supports CRI v1alpha2. We'll upgrade it to `v1.0.0-beta.1` soon after the release is cut.
2. Change `kube-docker-monitor` to `kube-container-runtime-monitor`, and let it use `crictl` to do health monitoring.
3. Change `e2e-image-puller` to use `crictl`. Because of https://github.com/kubernetes/kubernetes/issues/63355, it doesn't work now. But in `crictl v1.0.0-beta.1`, we are going to statically link it, and the `e2e-image-puller` should work again.
4. Use `systemctl kill --kill-who=main` instead of `pkill`, the reason is that:
a. `pkill docker` will send `SIGTERM` to all processes including `dockerd`, `docker-containerd`, `docker-containerd-shim`. This is not a problem for Docker 17.03 CE, because `containerd-shim` in containerd 0.2.x doesn't exit with SIGERM (see [code](https://github.com/containerd/containerd/blob/v0.2.x/containerd-shim/main.go#L123)). However, `containerd-shim` in containerd 1.0+ does exit with SIGTERM (see [code](https://github.com/containerd/containerd/blob/master/cmd/containerd-shim/main_unix.go#L200)). This means that `pkill docker` and `pkill containerd` will kill all shim processes for Docker 17.11+ and containerd 1.0+.
b. We can use `pkill -x` instead. However, docker systemd service name is `docker`, but daemon process name is `dockerd`. We have to introduce another environment variable to specify "daemon process name". Given so, it seems easier to just use `systemctl kill` which only requires systemd service name. `systemctl kill --kill-who=main` will make sure only main process receives SIGTERM.

It is possible that the node API object doesn't exist in a brief
window between recreation and registering. By moving the uncordon
until after the node is ready, we can be sure the API object exists.

Bump down to cos-stable-65 in config-test
Until https://github.com/kubernetes/kubernetes/issues/62456 is fixed (and we have a good patched version of cos-66), we probably should not be using the current version for testing which we anyway know we wouldn't be using for prod due to the bug.

gcp: allow non-bootstrap kubeconfig
**What this PR does / why we need it**:
Needed for https://github.com/kubernetes/community/pull/2022
This change lets us generate a non-bootstrap kubeconfig with exec plugin for authn.
The plugin does TLS bootstrapping internally.

Defaults when no new env vars are set will behave same as before this change.
`KUBELET_AUTH_TYPE` should never be `tls-auth` in practice, but leaving it there just in case.

Update all script shebangs to use /usr/bin/env interpreter instead of /bin/interpreter
This is required to support systems where bash doesn't reside in /bin (such as NixOS, or the *BSD family) and allow users to specify a different interpreter version through $PATH manipulation.

Use /usr/bin/env in all script shebangs to increase portability.
