amazonInstaller script, update or not support

On the InfiniDB product,we have a script that will automatically will setup an Amazon System based Parameters provide by user in a configure file. This script, called amazonInstaller is pre-installed on the AMI. It will auto create all the instances and EBS volumes foe the user.

This script needs to be updated to work on the ColumnStore product or we can decide just to use the postConfigure installer, which will also pre-create the instances and EBS volumes for the user. The main difference is postConfigure is a prompting configuration tool and the amazonInstaller reads the dat from the configuration file, making it a quicker installer to bring up a multiple-node cluster.
