I suggest to remove this pass-through method, as it at a very low
abstraction level. This information can be obtained already from the result of
`getKeyGroupRange()`. Now, that we expose the `KeyGroupRange`, also
`getNumberOfKeyGroups()` could be removed, as we can ask the `KeyGroupRange`
directly.
