[christian-pinto]

This issue creates a reference implementation of a Sunfish agent handling a CXL fabric

@rherrell please add details

More specifically, this reference implementation will be used to instantiate an Sunfish Agent instance that will serve up a set of CXL fabric mockups by registering with an instance of the Sunfish sunfish_server_reference. The Sunfish Server will then upload the CXL Fabric mockups pre-loaded into this Agent instance.

Initial versions of this Agent instance will be more development code and not as modular as later versions.
