Spectral ruleset to check that referenced interfaces are defined on the specific node

[willosborne]

Feature Request

Description of Problem:

Currently spectral rules check that referenced interfaces are defined.
It does not check that they're defined on the specified node - so this could potentially cause some confusion.

Potential Solutions:

Either enhance the existing rule to check the node that owns that interface, or make a new rule that performs this check.

Another rule - check for erroneous ref values. Everything should be $ref and 'ref' should be an error.

@willosborne was this implemented?

@jpgough-ms no, this is still unimplemented
