Change subject: KUDU-2612 p3: tserver mechanism to create txn status tablets ...................................................................... KUDU-2612 p3: tserver mechanism to create txn status tablets This introduces the concept of a table type in tablets. This is used in the context of creating transaction status table partitions; if a tablet replica is created as a partition of a transaction status table, the underlying replica will initialize some state to manage and coordinate transactions -- namely, a TxnStatusManager. For the sake of decoupling submodules, to get a TabletReplica to initialize a TxnStatusManager, this patch introduces the tablet::TxnCoordinator and tablet::TxnCoordinatorFactory interfaces that TxnStatusManager and the new TxnStatusManagerFactory implement respectively. The TxnStatusManagerFactory can be created by members of the tserver and passed to TabletReplicas upon initialization -- this layer of indirection will allow us to use tserver-wide state (e.g. in the future, a system client) without muddying the tablet subdirectory too much. The plumbing only extends through the tablet servers -- the ability to create transaction status tables and define partitioning is not yet plumbed into the master.
