CREATE SCHEMA OBJECTS fix

    INITIALIZE TRAFODION,CREATE SCHEMA OBJECTS would fail if a
    schema to be created was not a regular identifier.  Now
    names are delimited.

    Also fixed a REVOKE ROLE problem where an unitilized variable
    could lead to a core.

    Updated HIVE tests to include CREATE SCHEMA commands.
