Add time limit for successfully deploying

- Add config var for max wait time for a deployment
- Move exit function and trap to the beginning of the script
- Execute the rollout status command using timeout
-- Use signal 2 (SIGINT; same pressing CTRL+C)
-- Abort the command if it is still running when max time is reached
-- If the command was aborted, rollback this deployment
