Add shim documentation to the website.

Add three new doc pages to the website.

- A containerd quick start covering containerd 1.2. This is limited to shim v2
  and runtime class as the docs would get too complicated explaining all the
  combinations that are possible. We want folks to use shim v2 and runtime
  class anyway.
- An advanced configuration page. This covers containerd and
  containerd-shim-runsc-v1's configuration options.
- A page for old versions (i.e. containerd 1.1). Notes that this is deprecated
  and supported on a best-effort basis.

Fixes #3279

-# Runtime Handler Quickstart (Shim V2)
-
-This document describes how to install and run `containerd-shim-runsc-v1` using
-the containerd runtime handler support. This requires containerd 1.2 or later.
-
-## 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 containerd-shim-runsc-v1
-
-1.  Build and install `containerd-shim-runsc-v1`.
-
-<!-- TODO: Use a release once we have one available. -->
-
-[embedmd]:# (../test/e2e/shim-install.sh shell /{ # Step 1\(dev\)/ /^}/)
-
-```shell
-{ # Step 1(dev): Build and install gvisor-containerd-shim and containerd-shim-runsc-v1
-    make
-    sudo make install
-}
-```
-
-### Configure containerd
-
-1.  Update `/etc/containerd/config.toml`. Make sure `containerd-shim-runsc-v1`
-    is in `${PATH}`.
-
-[embedmd]:# (../test/e2e/runtime-handler-shim-v2/install.sh shell /{ # Step 1/ /^}/)
-
-```shell
-{ # Step 1: Create containerd config.toml
-cat <<EOF | sudo tee /etc/containerd/config.toml
-disabled_plugins = ["restart"]
-[plugins.linux]
-  shim_debug = true
-[plugins.cri.containerd.runtimes.runsc]
-  runtime_type = "io.containerd.runsc.v1"
-EOF
-}
-```
-
-1.  Restart `containerd`
-
-```shell
-sudo systemctl restart containerd
-```
-
-## Usage
-
-You can run containers in gVisor via containerd's CRI.
-
-### Install crictl
-
-1.  Download and install the crictl binary:
-
-[embedmd]:# (../test/e2e/crictl-install.sh shell /{ # Step 1/ /^}/)
-
-```shell
-{ # Step 1: Download crictl
-wget https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.13.0/crictl-v1.13.0-linux-amd64.tar.gz
-tar xf crictl-v1.13.0-linux-amd64.tar.gz
-sudo mv crictl /usr/local/bin
-}
-```
-
-1.  Write the crictl configuration file
-
-[embedmd]:# (../test/e2e/crictl-install.sh shell /{ # Step 2/ /^}/)
-
-```shell
-{ # Step 2: Configure crictl
-cat <<EOF | sudo tee /etc/crictl.yaml
-runtime-endpoint: unix:///run/containerd/containerd.sock
-EOF
-}
-```
-
-### Create the nginx Sandbox in gVisor
-
-1.  Pull the nginx image
-
-[embedmd]:# (../test/e2e/runtime-handler/usage.sh shell /{ # Step 1/ /^}/)
-
-```shell
-{ # Step 1: Pull the nginx image
-sudo crictl pull nginx
-}
-```
-
-1.  Create the sandbox creation request
-
-[embedmd]:# (../test/e2e/runtime-handler/usage.sh shell /{ # Step 2/ /^EOF\n}/)
-
-```shell
-{ # Step 2: Create sandbox.json
-cat <<EOF | tee sandbox.json
-{
-    "metadata": {
-        "name": "nginx-sandbox",
-        "namespace": "default",
-        "attempt": 1,
-        "uid": "hdishd83djaidwnduwk28bcsb"
-    },
-    "linux": {
-    },
-    "log_directory": "/tmp"
-}
-EOF
-}
-```
-
-1.  Create the pod in gVisor
-
-[embedmd]:# (../test/e2e/runtime-handler/usage.sh shell /{ # Step 3/ /^}/)
-
-```shell
-{ # Step 3: Create the sandbox
-SANDBOX_ID=$(sudo crictl runp --runtime runsc sandbox.json)
