CSIT-775 HC Test: CRUD over IPv6 control-plane interface
Adds new test suite which accesses Honeycomb's Restconf and Netconf northbound over IPv6. This is done by sending the requests to TG where an IPv4 to IPv6 tunnel is configured to the Honeycomb DUT. Change-Id: I3b7467d8108b0da9756e632851215c66ed41bb61 Signed-off-by: selias <samelias@cisco.com>
