Increment the counter in the current bucket by one for the given {@link NumerusRollingNumberEvent} type.
<p>
The {@link NumerusRollingNumberEvent} must be a "counter" type <code>HystrixRollingNumberEvent.isCounter() == true</code>.

@param type
HystrixRollingNumberEvent defining which counter to increment
Boolean doNotBlock if currentBucket is null
