[3/3] nifi git commit: NIFI-2729: This closes #1270. testSendSuccessWithProxy timeout in Travis

NIFI-2729: This closes #1270. testSendSuccessWithProxy timeout in Travis

- Changed AtomicBoolean to CountDownLatch to avoid sleeping thread in
  some test cases
- Specified less number of threads for Jetty and LittleProxy than
  default to lower resource usage
- Added try catch for the specific gateway timeout case (504) so that
  test can pass even it happens while it fails with other errors
