Description

As we add more and more coordinator-related requests to the admin client, we can consider adding a CoordinatorNodeProvider to consolidate the common logic pattern of finding the coordinator first, then send the corresponding request.

Note that 1) with this provider interface it is almost not possible to batch multiple groupIds per coordinator; there has to be a little more refactoring to make it work. 2) for some requests like list consumers, group ids are not known beforehand and hence we cannot use this provider as well.
