[inputs.sqlserver] sqlserver plugin waits indefinitely if sqlservers responds very slow

[goswamisandeep]

Lets say we have a sqlserver which is very slow , and it responds to queries very slow . Current sqlserver plugin code does not have a timeout to cancel query execution .

In my setup we had a very slow sqlserver , it took almost 40 minutes for one iteration to get completed.
