Refactor data source configuration
This MR provides:
- Backend: list of data sources into the spring application.yml properties rather than having them listed in a resource file of the application.
- Frontend: card-generic-document component uniformizing the display of data sources and PUI on every card.
- Frontend: automatically updating of data sources in the nav bar
Move data sources to spring config
Refactor frontend display of data sources (add them on germplasm card)
Dynamically load sources in navbar (keep order, bonus: show only partners with data)
Rebase on master (After !18 (merged) is merged!)
