CKAN__DATAPUSHER__CALLBACK_URL_BASE ignored for data fetch

[jhbruhn]

I am using ckan behind a proxy which uses another internal authentication. Datapusher Plus (on the fixing-issues) branch is mostly aware of the CKAN__DATAPUSHER__CALLBACK_URL_BASE, but seems to be missing the DATAPUSHER_REWRITE_RESOURCES parameter present in the original datapusher implementation. This leads to an error while fetching data from the CKAN instance, while ironically the worker is on the same host/container in my case.

The actual location where the URL should be rewritten is here: https://github.com/dathere/datapusher-plus/blob/d28570ff295841b5c1392cb805eca8c8791b97f7/ckanext/datapusher_plus/jobs.py#L430
