gvisor-containerd-shim is not compatible with containerd 1.1 or earlier.
Starting from containerd 1.2, shim v2 is the preferred interface.

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

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).
