Write a regex to append ConfigureAwait(false) to ADO.NET commands

• 1 Find what:
  (await conn\.OpenAsync\(\))(?=(\s|\n)*[^\.])
  (await cmd\.ExecuteReaderAsync\(\))(?=(\s|\n)*[^\.])
  (await rd\.ReadAsync\(\))(?=(\s|\n)*[^\.])
  
• 2 Replace with:
  $1.ConfigureAwait(false)
  
• N Prevent deadlocks when the library code is called with synchronous blocking, improves performance a bit.
