That comment didn't seem to match the reality and confused me a bit. The
shim takes 3 arguments and the cwd is the containerd state directory.
I'm guessing it's a left over from the containerd split.

* gitignore: Use absolute paths
git status will only match the ignored path from the root of the
repository, a very slightly more accurate way to ignore those files.

* gitignore: Ignore the /output directory
Test artifacts are now generated in /output, so update the .gitignore
file accordingly.

To improve the output of module logging, we now include a path that
represents the modules that a context has passed through. This makes it
easy to tell if a log line came from a particular module hierarchy.
A helper function, `WithModule`, provides an easy way to mark a context
with a module and inject that module into the logger.

This fixes a sync issue when the containerd api returns after a
container has started. It fixes it by calling the runtime start inside
containerd after the oom handler has been setup.

Make sure that if we get an error from start it is returned and that we
reap the container's process from create before existing if we were to
send a kill signal.

This is the first in a series of micro benchmarks for containerd.
Performance measurement will use containerd objects and methods
that are not dependent on the grpc API and dont require the daemon
to the running. Test will require containerd-shim and runc.
The motivation is to understand the baseline performance at the lowest
containerd layer. A natural extension to this effort would be to write
macro benchmarks which would include API and daemon.
Note:
- Currently measures only one workload (busybox sh) start times. Will
add other bundles and args soon.
- Can use integration-test utils for bundle processing. However, json
marshal/unmarshal is currently timing out standard benchmark times. So
going with default spec for now.
