The gofumpt linter is a stricter drop-in replacement for gofmt. The
rules are ones that I strongly agree with and I think it would be better
if we added this linter instead of nit picking every PR.

It runs containers via CRI interface in a pod sandbox. This is the very
first version: I tried not to introduce any changes to common runner
interface.
There should be some CRI-speficic options for the runner (like polling
interval, as it doesn't have nice `Wait()` API), plus my plan so far is
to use OCI as the common layer for container options, so that we can
analyze OCI and translate to CRI (when possible, return errors when
option is not implemented).
CRI interface doesn't have a concept of 'unpacking' an image, so we
probably need to unpack via containerd API (or any other
runtime-specific API) by targeting CRI namespace.

This is preparation for implementing CRI runner.
CRI client moved into its own package, I split it into multiple files
and added rudimentary tests for it.

This makes test launch their own isolated instance of containerd with
its own root/state directories and listening socket address. Each test
brings this instance up/down on its own.
Add options to override containerd address in the code (used only in the
tests).
Enable parallel go test runs once again.
P.S. I wish I could share that 'SetupSuite' phase across the tests, but
afaik there's no way in Go to share `_test.go` code across packages. If
we put it as normal package, this might pull in test dependencies (like
`testify`) into production code, which I don't like.

This refactors metrics interface to remove containerd-specific stuff and
make it common for CRI & containerd.
