Clone notification support for bundles was added in commit b632ef0a in
the current upstream master branch. It hasn't made it into an upstream
release yet, but is expected to be in the next one.
It was backported to the RHEL 7.4 GA release, which is 1.1.16-12.el7.
The pre-release shown in your logs (1.1.16-10.el7-94ff4df) doesn't have
it.
