Translate the estimated Resource requirements of the pipeline to Hadoop's ReservationSubmissionRequest.

Parameters:

containerSpec - the Resource to be allocated to each container;

containerRequests - the predicted Resource to be allocated to the job in each discrete time intervals;

config - configuration file for BaseSolver.

Returns:

ReservationSubmissionRequest to be submitted to Hadoop to make recurring resource reservation for the pipeline.
