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).
This change renames the tools/images directory to tools/vm for clarity, and
adds a functional vm_test. Sharding is also added to the same test, and some
documentation added around key flags & variables to describe how they work.
Subsequent changes will add vm_tests for other cases, such as the runtime tests.

Change adds the following:
- logic to run from "baked images". See [GVISOR_DIR]/tools/images
- installers which install modified files from a workspace. This
allows users to run benchmarks while modifying runsc.
- removes the --preemptible tag from built GCE instances. Preemptible
instances are much more likely to be preempted on startup, which
manifests for the user as a failed benchmark. I don't currently have
a way to detect if a VM has been preempted that will work for this
change.

This formalizes the adhoc scripts previously in kokoro. The image targets can
be used by e.g. benchmarks in order to automated image prepation.
