Description

Currently the allocator's role tree only tracks the reserved resources for each role subtree. For metrics purposes, it would be ideal to track offered / allocated as well.

This requires augmenting the allocator's structs and recoverResources to hold the two categories independently and transition from offered -> allocated as applicable when recovering resources. This might require a slight change to the recoverResources interface.
