change makefile to accept "start" and "stop" to be able to start the testing environment and stopping it for manual testing purposes.

raising down-after-milliseconds of sentinel 1 to avoid taking the master down and up all the time.
change sleep to 10 seconds after doing a "salveof" to avoid false negatives.
