DynamicLoadBalancingPolicy: LatencyAwareHClientPool may throw NoSuchElementException under certain circumstances

In version 1.1-4, the call to "latencies.remove()" (LatencyAwareHClientPool  line 48) may throw a NoSuchElementException if the "resetThread" (See DynamicLoadBalancingPolicy instantiation line 62-74) clear the "latencies" LinkedBlockingDeque just before.

Using the poll() method instead of remove() should fix the issue.

How can i submit a patch ?

Thanks
