counterServiceId and counterPeerId is credentials to counter service for round-robin mode. Will be used local counter if undefined. quorumServiceId and quorumPeerId is credentials to counter service for round-robin mode. Will be used local counter if undefined. quorumNumber is 2 by default. quorumTimeout is how long we will wait for all responses requestTimeout is how long we will wait for aqua request
