e2f93d49d7
This change moves the KMIPProtocol class from the server module to the services module. Because the client uses KMIPProtocol, and KMIPProtocol lived in the server module, the client would end up importing server libraries whenever it was used. If there are any issues with server dependencies, this would cause the client to fail for no good reason. This change now insulates the client from the server code base and prevents this case from happening. See #509
