## What changes were proposed in this pull request? Users might want to start multiple mesos dispatchers, as each dispatcher can potentially be part of different roles and used for multi-tenancy. To allow multiple Mesos dispatchers to be launched, we need to be able to specify a instance number when starting the dispatcher daemon. ## How was the this patch tested? Manual testing Author: Timothy Chen <tnachen@gmail.com> Closes #11281 from tnachen/multiple_cluster_dispatchers.
