Detailed Description

Stores info pertaining to a single request made to ExecutorResourceMgr, including its request_id, min and max possible resource grants, actual resource_grant, and various timing stats.

In future work it is planned to use these stats to allow the ExecutorResourceMgr to learn from query patterns and timings over time to enable more efficient query scheduling.
