Expose findByQuery methods in public API of all modules

[TimoGlastra]

We want to expose some of the repository methods to the public api to allow better querying/updating support without needing to inject internal dependneices. A lot of modules already expose some repository methods (getAll, findById, etc..), but we should look to extend this.

This issue focuses on the findByQuery method, we should add it to all modules that expose a getAll method
