* Switch resource manager to a singleton which reduces the amount of

* Make the I_S tables use the FE implementation of the system catalog
* Make the I_S.columnstore_columns table use the RID list cache
* Make the extentmap pre-allocate a vector instead of many small allocs

lower limit to year 1000.
