> 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.
