> As [~dashengju] stated from STORM-738, very busy ShellBolt subprocess cannot respond heartbeat just in time.
> Actually it's by design constraint (more details are on STORM-513 or STORM-738), but ShellSpout avoids constraint by updating heartbeat at any type of response from subprocess.
> We can apply this approach to ShellBolt and let ShellBolt avoid design constraint, too.
