Description

Right now there is a different code path in the Driver for show tables/describe etc. By adding the FetchTask the code paths will be merged. In addition, the results of these statements will be readable via JDBC.

Going forward, we should provide SQL access to our metastore similar to access provided by Oracle or mysql to their catalog tables. In this jira, I will just add schema information to show tables and describe queries.
