Improvement description

Improve repository class to allow paging and filtering, necessary for studio. Related:https://github.com/pimcore/copilot-bundle/pull/696

E.g.

Has$limit and$offset parameter for paging, which is good. But it doesnt provide a way to apply filters.

Has$limit option only, but applies a filter to the state (=running).

Additionally, we also need to get thetotalCount not only for the whole table, but also for queries where we apply filters.
