acl: CLI allow replace, allow deletion
Allow the CLI caller to specify an optional [index <idx>] index, which will remove the ACL at that index. This mimicks the API behavior, Add a 'delete acl-plugin acl index <idx>' to mimick the API acl_del call, which will refuse to delete a non-existent index, as well as an index that is referenced by an interface. Type: improvement Signed-off-by: pim@ipng.nl Change-Id: I5f240f7a4e3bca14e8122917e8a5186d80094de2
