Automate the bulk loading of origins in a kubernetes job

The bulk loading of origins can be quite long.

The commands to launch [1] are in the toolbox so it could be possible to automate the process in a kubernetes job not have to launch everything manually.

The idea is to have a part in the helm chart that can handle that.

The information to have are:

• an url of a file containing the origins to load
• the task type
• possibly the origin batch size

Positive side effect:

• Job configuration is committed
• Logs are ingested in kibana

Tasks:

• Update the chart
• Update the documentation
