Description

Currently gridmix tries to gauge cluster load etc. and throttles job submission. This makes it unpredictable and also is hard to support across MR1 and MR2.

I propose we simplify it to be:

1. Replay mode - Just submit jobs in the interval as in the original trace.
2. Stress mode - Compress the interval with a given factor for all jobs.
