Creation of AWS images



Hello.
I've opened two PRs, both related to creation of images,
but none related to HVM images.

When playing with creation of images for unstable I've noticed
two problems in development branch.
(Sorry for inlining patches - mailing list rejects attachments).

One is related to checking whether image of that name already
exists; get_all_images() accepts named parameter owners, not owner:

 		ami_name = info.manifest.image['name'].format(**info.manifest_vars)

-		images = info._ec2['connection'].get_all_images(owner=['self'])
+		images = info._ec2['connection'].get_all_images(owners=['self'])
 		for image in images:
 			if ami_name == image.name:
 				msg = 'An image by the name {ami_name} already
exists.'.format(ami_name=ami_name)


Another is related to change of name of packages.
EC2 image tries to install dhcpcd package; unstable (and Jessie)
contains dhcpcd5. Wheezy also contains dhcpcd5 - maybe we should
change package to avoid problems for the next stable.
Here's the small, ad-hoc patch fixing it:
