Refactor Nuxeo Drive operations not matching Studio compatibility rules

The following operations have a signature that makes them impossible to use in a Nuxeo Studio automation chain

GetRepositories
["void", "list"]

NuxeoDrive.SetActiveFactories
["void", "boolean"]

With Studio application definition registries, users will soon be able to add Nuxeo Drive to their dependencies and automatically see all its content appear for them to use.

Unfortunately, they won't be able to use these operations in automation chains due to their signature, that should be among:

• void
• document(s)
• blob(s)

TODO
Provide operations that match Studio compatibility rules so that customers can use them in their Studio project
