[RFC] Role Assignment Protocol and Registrar: Add Role Assignment Protocol For Nodes and Registrar

[YugenSource]

Role Assignment Protocol and Registrar (RFC)

The Role Assignment Protocol acts as a decentralized or authority controlled way of assigning roles that can be verified to nodes. This protocol can be used to check on a Peers Assigned Role in the network and can be digitally signed by entities or use authority nodes to assign roles. These roles are modular and assigned by users.

Assigning Roles is useful as it means it will be easier to communicate with different nodes and more secure. The registrar can hold different registrations of nodes and can be done in a KAD with digital signatures in a decentralized manner.

It will sign a verified role and be viewable to the rest.
