[deltacloud-devel] Rightaws replaced by amazon-ec2 gem

[Michal Fojtik]

Hi,

I replaced RightAWS gem with Amazon-EC2.

Reasons:

- Amazon-EC2 is well supported by Amazon
 - RightAWS was pretty outdated and dunno if it's maintained
 - Amazon-EC2 is much faster in getting images / filtering compared to Right one.
 - Amazon-EC2 has some functionality which Right doesn't support:
   - Uploading userdata in Base64 form
   - Filtering images (kernel/ramdisk/public/own...)
   - Add keypair when starting an instance

I tested this 'new' driver against real EC2 and everything is working fine.
Let me known if it works for you as well and if there is some reason why we
want to keep right-aws gem.
