With auto_bridge_add defined as:
auto_bridge_add:
# nothing here
helm doesn't treat is as am empty table so issues warnings such as:
2017/10/03 19:24:37 warning: destination for auto_bridge_add is a table. Ignoring non-table value <nil>
This happens most of the time as we use `helm --values=...` to augment
values.yaml in the chart.
This change clarifies it is indeed a table and the warnings no long
appear.
