VPP-205: jvpp plugin support.

Splits jvpp into two jars
jvpp-registry.jar - base jvpp functionality
jvpp-core.jar - Java wrapper for vpe.api

Plugins can be generated the same way jvpp-core.jar is.
Example (nsh):
https://gerrit.fd.io/r/#/c/2118/

+This package contains basic tests for jvpp. To run the tests:
+
+- Make sure VPP is running
+- From VPP's build-root/ folder execute:
+  - sudo java-cp build-vpp_debug-native/vpp-api/java/jvpp-registry-16.09.jar:build-vpp_debug-native/vpp-api/java/jvpp-core-16.09.jar org.openvpp.jvpp.core.test.[test name]
+
+Available tests:
+CallbackApiTest - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
+CallbackJVppFacadeNotificationTest - Tests interface notifications using Callback based JVpp facade
+CallbackJVppFacadeTest - Execution of more complex calls using Callback based JVpp facade
+CallbackNotificationApiTest - Tests interface notifications using low level JVpp APIs
+ControlPingTest - Simple test executing a single control ping using low level JVpp APIs
+CreateSubInterfaceTest - Tests sub-interface creation
+FutureApiNotificationTest - Tests interface notifications using Future based JVpp facade
+FutureApiTest - Execution of more complex calls using Future based JVpp facade
+L2AclTest - Tests L2 ACL creation
