[Epic] Create Challenge microservice

[tschaffter]

The objective is to design and implement a REST API service for managing Challenge information. This information will be used first to fed data to the Challenge page (#685 ).

Update December 23, 2022

This week was dedicated to the development of the Challenge service, with a focus on implementing different types of filters for challenges. The outstanding tasks are listed above. They should be straightforward to implement thanks to the solutions already implemented. The only potential exception is the filtering by organization for two reasons:

• Organization information will be queried via the Organization service, instead of querying this info directly from the database.

• Think again about how to attach organization information to a challenge and what an organization is.

  • It should be possible to attach more than one "Challenge" Organizations to a given challenge, e.g. for a challenge co-organized by DREAM and MICCAI.
  • This requires to rethink who owns / has write access to the Challenge.
  • Should we also represent Sponsors like cloud providers, data providers, (scientific providers?) as Organizations and thus enable them to have their own organization page? E.g. IBM would have an org page in the registry where one can see all the challenges that IBM has supported and in what capacity for each challenge (data provider, cloud provider, scientific adviser).

  The first week of January will be dedicated to answer these questions - I will draft a proposal and submit it to the team - and complete this Epic.

I recently implemented full-text search. The last main feature to implement technology-speaking is how to get the challenge service and organization service to communicate.

The challenge microservice has been around for 2-3 sprints. There are improvements planned but they are out of scope for this Epic.
