system.batchlog will still have to be used while the cluster is upgrading from an older version, which doesn't know v2 yet. Re-add support for replaying v1 batchlogs. The switch to v2 will happen after the BATCHLOG_V2 cluster feature is enabled. The only external user -- storage_proxy -- only needs a minor adjustment: switch between the table names. The rest is handled transparently by the db/batchlog.hh interface and the batchlog_manager.
