> While attempting to recover a connection to a gremlin server that has gone offline, the Host object spawns many reconnect tasks
> The following code in Host.makeUnavailable() will always create and schedule a new Runnable no matter the value of reconnectionAttempt 
> {code}
>         reconnectionAttempt.compareAndSet(null,
>                 this.cluster.executor().scheduleAtFixedRate(() -> {
>                             logger.debug("Trying to reconnect to dead host at {}", this);
>                             if (reconnect.apply(this)) reconnected();
>                         }, cluster.connectionPoolSettings().reconnectInitialDelay,
>                         cluster.connectionPoolSettings().reconnectInterval, TimeUnit.MILLISECONDS));
> {code}
> It is just that the ScheduledFuture returned by scheduleAtFixedRate will be ignored if reconnectionAttempt != null.
