increase-scalegroup.pl

Add a system to an auto-scaling group.

This command increases the number of systems in an existing auto-scaling group by one, regardless of their current load or other conditons that would cause scaling to happen automatically. The group can be specified by the --group flag followed by a unique ID, or --host followed by the hostname pattern.
