HC Test: Fix intermittent failures of HC startup
- rework "check Honeycomb startup state" keyword - increase timeout value for startup - add separators to Honeycomb log file between test suites - other minor fixes: - remove usused import from NAT suite - fix loop in ICMPv6 ND proxy traffic script - add teardown to LISP cases - update prerequisites for sub-interface SPAN test Change-Id: I2f714ffc1d2e8435d3abe690d8bd15099e071c9a Signed-off-by: selias <samelias@cisco.com>
