/**
 * Creates a cluster of servers to be used for running multiple tests It performs the following tasks:
 * 
 * It creates a temporary directory using the test name
 * It creates a common configuration directory to be shared by all servers
 * It creates a runtime directory structure for each server in the cluster (data, log, lib)
 * It populates the configuration directory with multiple certificates (ca.pfx, server.pfx, user1.pfx, user2.pfx)
 *
