PG-320: Removing the query state code from the view.

Browse Source 
The query status monitoring code was used to track the current query state, for example,     
parsing, executing and finishing. After careful review, we have figured out that  
it does not make sense while a lot of time same query is running. Therefore it  
is also consuming resources. This commit will remove that feature. The upgrade
SQL from 1.0 - 2.0 is also updated.
