HC Test: ACL updates
- update low level ACL based on yang model changes - remove ietf-ACL test suite and test data and keywords - add ACL-plugin test suite, test data and keywords The ietf model of ACLs is no longer supported in Honeycomb. It has been replaced by the ACL plugin. Change-Id: Ic2c2a3e11c9717d1d3885275f6b868a0098343f9 Signed-off-by: selias <samelias@cisco.com>
