User-Data integration with Project Mercury

I've been working on better integration with EC2 user-data for Project Mercury. The goal is to allow users to specify configuration options when they launch a Mercury instance to simplify the process of manual configuration.

For example if you'd like the EC2 instance to receive an Elastic IP address you'd specify:
IP="new"
Or an existing elastic IP address:
IP="123.123.123.123"

Features that are currently working :

• Change the MySQL Password and also change it in Drupals settings.php.
• Set the username, password and email of Drupals Admin user (User 1).
• Create a new Elastic IP address or attach an existing Elastic IP to the EC2 instance.
• Set the servers hostnames (to be placed in /etc/hostname or /etc/hosts).
• Create a new EBS Volume (Create, Attach, Format and Mount the Volume).
• Attach and Mount an existing EBS Volume.
• Move existing data from the server to an EBS volume (or any other location such as /mnt).
• Use existing data on an EBS volume in place of data on the server.

Future features that'd like to work on include :

• Creating Raids from EBS volumes to increase I/O performance
• Automated backups of EBS volumes (based on Eric Hammonds script)

Currently this is a private image as I'm still fixing a number of bugs but I plan to release a beta or get these features into the next release of Project Mercury, if possible.
