Replace DataPusher

[BWibo]

DataPusher should be replaced

CKAN DataPusher is not a good choice for pushing data into CKAN datastore.
One core reason to replace DataPusher is that it is complicated to setup and extremly slow. Some more arguments are listed here.
I identified two candidates to replace DataPusher.

ckanext-xloader

Pros

• Comes as a CKAN extension and is easy to setup
• Up to 10x faster than Datapusher

Cons

• Needs to be included in the CKAN-SDDI image
• Can only be autoscaled by scaling CKAN instances
• All columns defined as text, and the Data Publisher will need to manually change the data types in the Data Dictionary and reload the data again.

DataPusher+

Pros

• Built on qsv, an ultra fast processing tool wirtten in Rust.
• Lives in a separate container and can be scaled individually

Cons

• Complicated setup
