HONEYCOMB-78: enable HC restart
Includes: - restart script for honeycomb - HONEYCOMBC-78 fix: jVPPRegistry.close() is not invoked in case of VPP restart. That prevents subsequent attempts to establish connection from failing (we cannot invoke vl_client_disconnect_from_vlib before connect_to_vpe on fresh vpp instance). Change-Id: Icf4d6a6a40605ed34d307a0f1405b8804ba5df53 Signed-off-by: Marek Gradzki <mgradzki@cisco.com>
