Resource Manager Framework

Resource Sharing Framework is based on Genius ID-Manager service. ID-Manager service manages resource/ID pools and allocates unique range of integer IDs for specific string keys. These key and ID/range mappings are persisted across controller restarts. The idea for resource sharing is to have common resource pools, managed by ID-Manager and allow applications to dynamically allocate a range of resource IDs for their use. The resource manager component of the framework creates resource Id pools for of-tables, groups, meters etc. Further, different applications can request for a number of resource-IDs from these pools. Same range is always returned across controller restarts.
