Add Resource describing cloud-init config

Registered by Steven Hardy on 2013-10-21

When the raw user-data patch lands ref blueprint raw-user-data, we can implement a resource which encapsulates the various options to cloud-init/cloud-config, whose Ref provides the user-data string which can be consumed by the OS::Nova::Server resource

Whiteboard

(stevebaker) I started on some resources, but it is turning out to be just string manipulation, so I'm now looking at doing most of this as intrinsic functions, specifically:

mime_multi_part: takes a list of strings (with optional content types) and formats them as a MIMEMultipart string.
as_yaml_str: takes a dict/list/whatever and writes it as a yaml formatted string. Useful for writing cloud-config with template structures rather than a block string

With these and raw-user-data it should be possible to make the most of cloud-init

    Implement as_yaml_str hot intrinisic function

    Allow intrinsic functions to be called in any order

    Implement multi_part_mime hot intrinisic function

(stevebaker) Depending on hot-software-config, since the current approach is to implement a cloud-config resource and a multipart-mime resource which both subclass the SoftwareConfig resource.
