Fixed possible memory leak in ScheduledThreadPoolExecutor (HystrixTimer.java) #1976
Found what seems to be a possible memory leak inside HystrixTimer.java caused by cancel operations called on tasks inside a ScheduledThreadPoolExecutor.
The fix helped us and solved the leakage.
Tasks that were canceled due to timeouts were not removed from the scheduler queues unless setRemoveOnCancelPolicy(true) was called on that scheduler on initialization.
