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.

```release-note
Use /usr/bin/env in all script shebangs to increase portability.

The regular kubeconfig is fetched from metadata when
CREATE_BOOTSTRAP_KUBECONFIG==false.

Use BootID instead of ExternalID to check for new instance
PR #60692 changed the way that ExternalID is reported on GCE. Its value

upgrade will check that the boot ID changed.

Add unit test for configure-helper.sh.
**What this PR does / why we need it**:
Add a framework for unit-testing configure-helper.sh.
configure-helper.sh plays a critical role in initializing clusters both on GCE and GKE. It is currently, over 2K lines of code, yet it has no unit test coverage.
This PR proposes a framework/approach on how to provide test coverage for this component.
Notes:
1. Changes to configure-helper.sh itself were necessary to enable sourcing of this script for the purposes of testing.
2. As POC api_manifest_test.go covers the logic related to the initialization of apiserver when integration with KMS was requested. The hope is that the same approach could be extended to the rest of the script.
