api: API trace improvements
Type: improvement * add support for JSON format in API trace * add ability to replay JSON API trace in both VPP and VAT2 * use CRC for backward compatibility check during JSON API replay * fix API trace CLI (and remove duplicits) * remove custom dump * remove vppapitrace.py * update docs accordingly Change-Id: I5294f68bebe6cbe738630f457f3a87720e06486b Signed-off-by: Filip Tehlar <ftehlar@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com>
