+* `dynamic_partition.hot_partition_num`

+ Specify how many of the latest partitions are hot partitions. For hot
partition, the system will automatically set its `storage_medium` parameter to
SSD, and set `storage_cooldown_time`. Assuming that the partition is divided by
day and the parameter is set to 2, then the partitions of the last 2 days,
`storage_medium` are all SSDs. The `storage_cooldown_time` of yesterday's
partition is 0 o'clock tomorrow, and the `storage_cooldown_time` of today's
partition is 0 o'clock the day after tomorrow.
Review comment:
Would it be better to point out that the latest partition is the
`current partition` rather than `dynamic_partition.end` partition?
