A Schema should not have to know its name and parent. We should remove the following methods from the `Schema` SPI:
This will potentially allow schemas to be used more than once in the schema-hierarchy, with different names and parents; or even in different schema-hierarchies.
The `name` and `parent` parameters in `SchemaFactory.create(SchemaPlus parent, String name, Map<String, Operand> operand)` will remain. The schema factory might find them useful. But the schema created does not need to remember them.
The `SchemaPlus` wrapper added by Optiq will remember a schema's name and parent.
