`quorumServiceId` and `quorumPeerId` is credentials to counter service for `round-robin` mode. Will be used local counter if undefined.
`quorumNumber` is `2` by default.
## Mode ## Mode
`random` - choose providers randomly `random` - choose providers randomly
`round-robin` - choose providers in circle order `round-robin` - choose providers in circle order
`quorum` - call all providers and choose the result that is the same from `>= quorumNumber` providers. Or return an error.
