Add support for DeployArtifactURLs

Adds a new nested stack deployment which allows operators to
opt-in to deploy tarball's and RPM packages by setting
DeployArtifactURLs as a parameter_default in a Heat
environment.

The intent is to use this setting to allow t-h-t to
transparently deploy things like tarballs of puppet modules
via a Swift Temp URL.
