Add an Amazon template for building AMIs

The differences between this builder and the openstack one are the cloud
specific options passed, and the disabling of ANSIBLE_PIPELINING.

For some reason ansible is not able to set up the local ssh connection
(ssh <ssh_user>@127.0.0.1) on the EC2 instance after transfering the
playbook files, yet it can successfully ssh to the machine.

Disabling the pipelining support opens a new ssh connection each time
ansible runs a task. This takes more time, but works.

This patch also includes an amazon cloud example var file.
