> LlapTaskCommunicator uses sync client to send task attempts. There are fixed
> number of communication threads (10 by default). This causes unneccessary
> delays when there are enough free execution slots in daemons but they do not
> receive all the tasks because of this bottleneck. LlapTaskCommunicator can
> use an async client to pass these tasks to daemons.
