> Currently, if one famework launched tasks in all resources, the other framework has to wait those tasks completed to get deserved resources. That's un-fair to the new framework, there're several EPICs on such case but still can not resolve it:
>     - Quota: balance resouces based on un-allocated resources; the used resources can not be reclaim back when new framework registered
>     - Optimistic Offer Phase 1 (oversubscription of reservation): the un-used reserved resources can be used by the new framework; but still can not reclaim un-reserved resources back.
>     - Optimistic Offer Phase 2: in phase 2, all resources are offered to all framework; besides resources conflict, it also need to re-shuffle resources if one framework over occupied.
> The target of this EPIC is to
>     1. Enhance DRF to identify which resources should be reclaim
>     2. Define the protocol between Mesos & Framework to reclaim resources gracefully
> To keep the compatibility, this feature is controlled by master paramenter, e.g. --enable-reclaim.
