https://bugzilla.redhat.com/show_bug.cgi?id=1223257
https://bugzilla.redhat.com/show_bug.cgi?id=1223278
From above BZ update pipeline.yaml to include hardware support

1. Install rdo-manager in a virtual environment on RHEL
2. Deploy undercloud
3. Deploy overcloud
4. Run 'ceilometer meter-list' on the undercloud node, no meters are showing. central.log shows error.

Actual results:
no hardware meters shown from 'ceilometer meter-list'

Expected results:
hardware meters should be displayed
