Arksine 53ad4cb493 history: store job keys as zero padded hex values
This ensures that jobs in the database will be stored in the order they were started.  Doing so also eliminates the need for the `history_auto_inc_id", as we can initialize the next id from the database keys.

This also caches history keys in memory so we do not need to read them from the database on each access.
