[gentoo-catalyst] Feature - add support for Amazon EC2

[Proneet Verma]

Hi,

I would like to add a feature to the catalyst project. I would like to
deliver the following:

Catalyst <https://www.gentoo.org/proj/en/releng/catalyst/> module which
would be used to build AMI (amazon machine images) and upload it directly
to the AWS

   - Catalyst currently produces Gentoo stages using spec files into which
   I would add a feature to build AMIs in the same manner by using the spec
   file.
   - In this manner, user can generate AMIs from latest stages and
   configure their system in whatever fashion they want without bloating there
   system with pre-generated stages (which have unnecessary packages).
   - 'rich0' (gentoo-dev Richard Freeman) has very nicely blogged about how
   to bootstrap Gentoo on EC2
[here<http://rich0gentoo.wordpress.com/2012/09/24/gentoo-ec2-tutorial-bootstrapping/>
   ] which I would be following to write this module up inside of catalyst
   for which I would be using Python.
   - User would be expected to provide their AWS related information (like
   region, key pair).

Currently, I'll be concentrating on AWS only but would be extending this to
Openstack, Virtualbox, DigitalOcean. I have a brief idea about the catalyst
module (3.0 branch) and have been following as well as contributing (some
minor bug fixes) it from past few months. I'd be really happy to contribute
to the gentoo community.

Please give me your feedback.

Regards,
