This removes the metric vec that was holding onto all task id and
namespace combinations forever, until containerd was restarted. This
was causing a memory leak with many task.
This also removes the shim cmd where the `Args` is quite large from the
reaper after the shim has been started cutting down on another leak.
This is the first pass through the reaper but more code is required to
fix all the issues when commands are added.

This changes Wait() from returning an error whenever you call wait on a
stopped process/task to returning the exit status from the process.
This also adds the exit status to the Status() call on a process/task so
that a user can Wait(), check status, then cancel the wait to avoid
races in event handling.

Since we now have a common set of error definitions, mapped to existing
error codes, we no longer need the specialized error codes used for
interaction with linux processes. The main issue was that string
matching was being used to map these to useful error codes. With this
change, we use errors defined in the `errdefs` package, which map
cleanly to GRPC error codes and are recoverable on either side of the
request.
The main focus of this PR was in removin these from the shim. We may
need follow ups to ensure error codes are preserved by the `Tasks`
service.

These rpcs only return pids []uint32 so should be named that way in
order to have other rpcs that list Processes such as Exec'd processes.

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.
