Remove client code from apex-pdp

Removal of the deployment and monitoring client from the apex-pdp as
the functionality is replaced by the Policy Framework deployment using
PAP and the Policy Framework monitoring GUI.

Code in the engine proper that was used to administer apex-pdp over the
Web Socket port is also removed, as this code was only used by the
apex-pdp legacy GUIs.

Issue-ID: POLICY-2621
Change-Id: Ib9fc4a667a4bc79377bb7b82fae6a2bd520a3e3d
