CSIT-424: HC Test: JSON comparison function rework
When comparing multi-level JSON trees, the exceptions raised carry more useful information. Keys and values not present in reference data are ignored. No longer puts chunks of honeycomb's log file into robot report. The entire log file will be archived after https://gerrit.fd.io/r/4171 Change-Id: Ib597080fa3d9b2c43463c76ee0d52f317ea072e7 Signed-off-by: selias <samelias@cisco.com>
