Change subject: KUDU-2612: add RPC to send participant ops ...................................................................... KUDU-2612: add RPC to send participant ops This adds methods to the TxnSystemClient to send participant ops to participants by their tablet ID. This will be used in steps 13 and 18 of the transactions write path[1]. The new ParticipantRpc abstraction borrows a lot from CoordinatorRpc with regards to lookups and error handling, with the following differences: - Rather than doing the lookup by table and partition key, it performs a lookup by tablet ID, using the functionality recently added to the MetaCache. - Since TxnParticipants don't return success on repeated participant op requests calls, some additional handling is done for the TXN_OP_ALREADY_APPLIED error code.
