Fixed SQL Server config confirmation query.
vNext
Improving the SQL error reporting to be easier to read for the user.
Added user name and interactive mode to the logs to make support easier. Changed '--collect-only' argument to '--test' or '-t' because it conveys the meaning better and is easier to type. The '--collect-only' arg is still supported, but not documented. Generally cleaned up the logging messages to help the user understand what is happening.
