Why I did it
To allow users to add ACL rules w/ ICMP and VLAN qualifiers via acl-loader.
Need a separate PR from #6896 because 201911 is still using python2.
How I did it
Added
sonic-acl-extension.yang
to augment the existing OpenConfig spec and used pyangbind to generate a new set of python bindings.How to verify it
Re-run the ACL tests w/ the new openconfig_acl.py script and verify that all rules are still loaded properly and dataplane behavior is not impacted.
