Extend the DESCRIBE statement to more useful information

[sriramsub]

DESCRIBE (extended) statement to report on originating SQL and other useful information (created-timestamp, sql create statement, stream topology, basic metrics <number of events, last event timestamp, number of errors/exceptions>, underlying kafka-topic) (future: permissions, group, creator etc) (should this be part of show query instead?)

Yes, we can have DESCRIBE queryId to show the above information for the stream job associated with the query.
We should also extend the current DESCRIBE for streams/tables to include more information.
