- Add log statements in service entry points.
- Propagate `-debug` flag from shim invokation to the service
- Load options when shim process is invoked to ensure runsc commands
use the correct set of options, e.g. --debug --debug-logs=...
- Add debug options to the shim configuration directly, so it doesn't
rely on containerd configuration (and restart) to enable shim debug.
- Save shim logs to dedicated file, so it's easier to read logs. They
would be mixed with containerd logs and hard to distinguish
otherwise.

This was causing gvisor-containerd-shim to crash because the command
suceeded, but there was no stat present.

Using the newer bazel rules necessitates a transition from proto1 to
proto2. In order to resolve the incompatibility between proto2 and
gogoproto, the cri runtimeoptions proto must be vendored.
Further, some of the semantics of bazel caching changed during the
transition. It is now necessary to:
- Ensure that :gopath depends only on pure library targets, as the
propagation of go_binary build attributes (pure, static) will
affected the generated files (though content remains the same,
there are conflicts with respect to the gopath).
- Update bazel.mk to include the possibility of binaries in the
bazel-out directory, as it will now put runsc and others there.
This required some refinements to the mechanism of extracting
paths, since some the existing regex resulted in false positives.
- Change nogo rules to prevent escape generation on binary targets.
For some reason, the newer version of bazel attempted to run the
nogo analysis on the binary targets, which fails due to the fact
that objdump does not work on the final binary. This must be due
to a change in the semantics of aspects in bazel3.

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).
