Map sql errors to messages that user see

There is a number of errors that user can get during sql command execution. Map all types of errors and map them to exit error codes and user messages. Also, a user has to understand what is wrong with the query. Now it displays jusn an abstract message.

How it works now:

sql-cli> create table myta
SQL query parsing error: Sql query execution failed.
sql-cli> 

sql-cli> create table mytable(i int, j int);
Unrecognized error while process SQL query.
sql-cli> 

"SQL query parsing error: Sql query execution failed.", "Unrecognized error while process SQL query."  say nothing about what exactly is wrong.
