> TableParentConfiguration is a shim class between Table and Namespace configuration. 
It exist on the premise that a table may move between namespaces.  However this is currently
not possible in Accumulo and would require a major redesign the make it possible.  This class
always spend time looking up a tables namespace id each time a table property is accessed.
However this Id will never changes.
> Also should a tables namespace ever change, the current config code is not correct because
not all code looks up the namespace id.
> TableParentConfiguration should be removed.
