Adds support for "show create table", a DDL statement that outputs a DDL statement that creates the specified table. In general, the output DDL works in Impala, so a user can copy the output and execute it to create the same table. However, there are a few special cases that output Hive DDL because we do not support creating some tables in Impala: HBase tables and tables with LZO compressed text. When we do support creating these tables in Impala, users should be able to execute the DDL in Impala as well.
