DATAKV-176 - Adapt to API changes in repository interfaces.

We now follow a more consistent naming scheme for the methods in repository that are driven by the following guidelines:

* Methods referring to an identifier now all end on …ById(…).
* Methods taking or returning a collection are named …All(…)

Please see DATACMNS-944 for details.
