The 'resources' in the pipeline definition is a list of endpoints for
the pollsters to get the data from. It's optional and it's up to the
specific pollsters to decide how to use it.
The new pipeline definition could be something like the following:
meters:
- "*"
resources:
- file:///foo/bar/endpoints
Implements: blueprint support-resources-pipeline-item
