Changes to handle PDPX deploy/undeploy
Added changes to handle incoming udpate for deploying or undeploying the policies by comparing both sets. STill need to add support for removing the policies and getting the deployed ToscaPolicyIdentifiers for PdpStatus response. * PLD - added functionality to unload policies in the applications and * PLD - added map of loaded policies * Mike - made change to address Jim's and Joshua's comments * Mike - Made change to use mapLoadedPolicies to get deployed policies from the applications * Mike - made change to assembly.xml to add support for apps directory.
