Fully specified individual server configuration object model

The fully-specified domain model representation of an individual server. This is not the <server> element in a host.xml, as that is simply the server-level extensions and overrides of configuration expressed elsewhere. Rather, this is the merged combination of the relevant domain, server-group, host and server information from domain.xml and host.xml, or from the equivalent configuration file(s) for a standalone server.

Initially we are going to use the Standalone class for this, which is the proposed class into which a standalone server configuration would be parsed. It's possible that will change if using the same class for both proves problematic.
