Description

Need to modify Split procedures to deal with meta, and also remove all the hard coded non-splittable check for meta region.

And we also need to think of the split policy for meta table, i.e, whether it is safe tosplit at any point. For safety, maybe we could first use a special split policy to make sure that all records for a table are in the same region.
