E20-655 Web TestEngine demo

The job daemons on each node attempt to lock a file and the one that succeeds becomes the coordinator.

The nodes share performance data with the job daemons and the daemon on the node with the lightest load becomes the coordinator.

The storage administrator selects a node to run the coordinator based on the cluster architecture.

The job daemons generate random numbers, and the one that generates the lowest number becomes the coordinator.
