mongoose.disconnect won't stop the connection if a reconnect is in progress

What is the current behavior?

When using autoReconnect: true, the connection to mongodb is automatically restored once the database is up again. However if mongoose.disconnect() is invoked when the connection is in a disconnected state, the connection is not really terminated and would proceed with the automatic reconnection.

This can be a problem in a production environment when a graceful shutdown of the application would hang if one connection is currently waiting to reconnect.

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

The mongoose.disconnect method should prevent reconnection from happening, allowing the process to exit.
