Kevin Carter 621c552e23 Add retry to execution commands ... There are quite a few instances where the "exec_command" function fails due unrelated issues. This change adds a retry with a backoff. The exec function will now retry 3 times in the event of an exception with a cool down of 2 seconds. The play context for retries will also be set if undefined making it possible to recover from transient UNREACHABLE errors.
