Implement syntax like: create table t1 (x int) with system versioning partition by system_time; which will create 1 history partition and 1 current partition. Also it is possible to specify the number of history partitions: create table t1 (x int) with system versioning partition by system_time partitions 5; which will create 4 history partitions (and 1 current partition). Tests: partition.test cases are duplicated where it is appropriate for default partitions. partition_rotation.test cases are replaced by default partitions where possible.
