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.
