This commit enables users to start Kraken to act as listener by setting the signal to PAUSE in the config to get the cluster to a desired test or run any setup before injecting chaos by setting the signal to RUN. This helps in cases where we have test cases that need to coordinate the chaos at a desired time depending on the state of the cluster/test run.
