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).
