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.
Sample run:
BenchmarkBusyboxSh-4 / # / # / # 2 576013841 ns/op

See https://github.com/docker/docker/issues/22643 for an example
where we get an error running a cmd but there's no output so `b`
is an empty string, which means the user doesn't see any interesting
error message to help them.
This PR will send back the `err` and `b` so that between those two
bits of info they should get something more than a blank string.

On arm64, the default build flag is the same as the one from
`go env` which is arm64. So we should use arm64 instead of
aarch64 for both build flag and file name.

Because we are launching alot of different runc commands to do
operations there is a race between doing a `cmd.Wait()` and getting the
sigchld and reaping it. We can remove the sigchild reaper from
containerd as long as we make sure we reap the shim process if we are
the parent, i.e. not restored.

runc `events --stats` now has stable output so we don't need to bind to
libcontainer directly to get stats output for the containers.

runc now has a `ps` command with json output to support listing all the
processes inside a container. We no longer need to use libcontainer
directly for doing this.
