Michael Crosby 6d71e61742 Add GC loop to clean exec command refs on daemon ...

This adds an event loop for running a GC cleanup for exec command
references that are on the daemon.  These cannot be cleaned up
immediately because processes may need to get the exit status of the
exec command but it should not grow out of bounds.  The loop is set to a
default 5 minute interval to perform cleanup.

It should be safe to perform this cleanup because unless the clients are
remembering the exec id of the process they launched they can query for
the status and see that it has exited.  If they don't save the exec id
they will have to do an inspect on the container for all exec instances
and anything that is not live inside that container will not be returned
in the container inspect.
