Authorization api: missing privilege objects in create table/view

Issues being addressed:

• In case of create-table-as-select query, the database the table belongs to is not among the objects to be authorized.
• Create table has the objectName field of the table entry with the database prefix - like testdb.testtable, instead of just the table name.
• checkPrivileges(CREATEVIEW) does not include the name of the view being created in outputHObjs.
