Update shim to build using bazel.

The go.mod dependency tree for the shim was somehow contradictory. After
resolving these issues (e.g. explicitly imported k8s 1.14, pulling a
specific dbus version), and adding all dependencies, the shim can now be
build as part of the regular bazel tree.

As part of this process, minor cleanup was done in all the source files:
headers were standardized (and include "The gVisor Authors" in addition
to the "The containerd Authors" if originally derived from containerd
sources), and comments were cleaned up to meet coding standards.

This change makes the containerd installation dynamic, so that multiple
versions can be tested, and drops the static installer for the VM image
itself.

This change also updates test/root/crictl_test.go and related utilities,
so that the containerd tests can be run on any version (and in cases
where it applies, they can be run on both v1 and v2 as parameterized
tests).

-# Untrusted Workload Quickstart
-
-This document describes how to install and run the `gvisor-containerd-shim`
-using the untrusted workload CRI extension. This requires containerd 1.1 or
-later.
-
-*Note: The untrusted workload CRI extension is deprecated by containerd. If you
-are using containerd 1.2, please consider using runtime handler.*
-
-## Requirements
-
-- **runsc**: See the [gVisor documentation](https://github.com/google/gvisor) for information on how to install runsc.
-- **containerd**: See the [containerd website](https://containerd.io/) for information on how to install containerd.

-## Install
-
-### Install gvisor-containerd-shim
-
-1. Download the latest release of the `gvisor-containerd-shim`. See the
-   [releases page](https://github.com/google/gvisor-containerd-shim/releases)
-
-[embedmd]:# (../test/e2e/shim-install.sh shell /{ # Step 1/ /^}/)
-```shell
-{ # Step 1(release): Install gvisor-containerd-shim
-LATEST_RELEASE=$(wget -qO - https://api.github.com/repos/google/gvisor-containerd-shim/releases | grep -oP '(?<="browser_download_url": ")https://[^"]*gvisor-containerd-shim.linux-amd64' | head -1)
-wget -O gvisor-containerd-shim ${LATEST_RELEASE}
-chmod +x gvisor-containerd-shim
-sudo mv gvisor-containerd-shim /usr/local/bin/gvisor-containerd-shim
-}
-```
-
-2. Create the configuration for the gvisor shim in
-   `/etc/containerd/gvisor-containerd-shim.toml`:
-
-[embedmd]:# (../test/e2e/shim-install.sh shell /{ # Step 2/ /^}/)
-```shell
-{ # Step 2: Create the gvisor-containerd-shim.toml
-cat <<EOF | sudo tee /etc/containerd/gvisor-containerd-shim.toml
-# This is the path to the default runc containerd-shim.
-runc_shim = "/usr/local/bin/containerd-shim"
-EOF
-}
-```
-
-### Configure containerd
-
-1. Update `/etc/containerd/config.toml`. Be sure to update the path to
-   `gvisor-containerd-shim` and `runsc` if necessary:
-
-[embedmd]:# (../test/e2e/untrusted-workload/install.sh shell /{ # Step 1/ /^}/)
-```shell
-{ # Step 1: Create containerd config.toml
-cat <<EOF | sudo tee /etc/containerd/config.toml
-disabled_plugins = ["restart"]
-[plugins.linux]
-  shim = "/usr/local/bin/gvisor-containerd-shim"
-  shim_debug = true
-[plugins.cri.containerd.untrusted_workload_runtime]
-  runtime_type = "io.containerd.runtime.v1.linux"
-  runtime_engine = "/usr/local/bin/runsc"
-  runtime_root = "/run/containerd/runsc"
-EOF
-}
-```
-
-2. Restart `containerd`
-
-```shell
-sudo systemctl restart containerd
-```
-
-## Usage
-
-You can run containers in gVisor via containerd's CRI.
-
-### Install crictl
-
-1. Download and install the crictl binary:
-
-[embedmd]:# (../test/e2e/crictl-install.sh shell /{ # Step 1/ /^}/)
-```shell
-{ # Step 1: Download crictl
-wget https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.13.0/crictl-v1.13.0-linux-amd64.tar.gz
-tar xf crictl-v1.13.0-linux-amd64.tar.gz
-sudo mv crictl /usr/local/bin
-}
-```
-
-2. Write the crictl configuration file
-
-[embedmd]:# (../test/e2e/crictl-install.sh shell /{ # Step 2/ /^}/)
-```shell
-{ # Step 2: Configure crictl
-cat <<EOF | sudo tee /etc/crictl.yaml
-runtime-endpoint: unix:///run/containerd/containerd.sock
-EOF
-}
-```
-
-### Create the nginx Sandbox in gVisor
-
-1. Pull the nginx image
-
-[embedmd]:# (../test/e2e/untrusted-workload/usage.sh shell /{ # Step 1/ /^}/)
-```shell
-{ # Step 1: Pull the nginx image
-sudo crictl pull nginx
-}
-```
-
-2. Create the sandbox creation request
-
-[embedmd]:# (../test/e2e/untrusted-workload/usage.sh shell /{ # Step 2/ /^EOF\n}/)
-```shell
-{ # Step 2: Create sandbox.json
-cat <<EOF | tee sandbox.json
-{
-    "metadata": {
-        "name": "nginx-sandbox",
-        "namespace": "default",
-        "attempt": 1,
-        "uid": "hdishd83djaidwnduwk28bcsb"
-    },
-    "annotations": {
-      "io.kubernetes.cri.untrusted-workload": "true"
-    },
-    "linux": {
-    },

-}
-EOF
-}
-```
-
-3. Create the pod in gVisor
-
-[embedmd]:# (../test/e2e/untrusted-workload/usage.sh shell /{ # Step 3/ /^}/)
