HeatContext model update to match heat code update

In Heat Liberty release OS::Nova::Server will always use the user
pre-configured in the image (e.g. "fedora" for stock Fedora cloud
images, "ubuntu" for stock Ubuntu cloud images, "cloud-user" for
stock CentOS cloud images etc)

Change all ec2-user -> ubuntu

Add admin-user in Heat model for backwards compatibility.
