Throw an error when a connection ends with a RST,ACK packet?

According to MySQL docs, COM_QUIT command should end with “either a connection close or a OK_Packet”.

As @elemount pointed out in issue #1730, Azure MySQL is answering with an RST,ACK.

It can be reproduced when you run this example code against an Azure MySQL instance.

var mysql      = require('mysql');
var connection = mysql.createConnection({ config });

connection.connect();

connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
  if (error) throw error;
  console.log('The solution is: ', results[0].solution);
});

connection.end();

Throws ECONNRESET error.

Should this library throw an error when a connection end with a RST with the ACK flag set? Can we detect this?

@alex030293 provided a connection to a MySQL Azure instance and I reproduced the issue and have a tentative fix. I should land the fix on master today once I get it cleaned up.

I have a failing branch pushed up right now. Still need to get Azure set up and finish the changes. This is what is holding the next release, so yes it is expected in the next release.
