Description

The MRP may fail due to some reason, so we need to add some checks in ReopenTableRegionsProcedure, if we fail to reopen a region, then we should schedule a new MRP for it again.

And a future improvement maybe that, we can introduce a new type of procedure to reopen a region, where we just need a simple call to RS, and do not need to unassign it and assign it again.
