Current implementation of the Batch Report can be improved.
Protobuf format :
- some fields and/or their denormalisation are now useless (componentRef)
- clean up measure fields
- variations of any use now?
- rule_key and characteristic_id can actually be sent by the batch?
- quid of perso_id? (what's the status of DevCockpit?)
- no more need for alter_status nor alert_text (now computed in CE)
- clean up Issue
- what's the difference between duplication and duplicate?
- fix TODOs
- there should not be any intermediate structure so that read/write from/to file can be streamed
- ReportReader must be refactored to support streams
