Description

A client's dominant share is crucial measure for how likely it is to receive offers in the future. We should expose it in a dedicated allocator metric.

As currently the HierarchicalAllocatorProcess does work with generic Sorters which have no notion of DRF share we need to decide whether and where we would need to limit generality in order to expose the innards of the currently used DRFSorter.
