Enhancement: Add Notes to 'submit_order'

[Jacyle]

Could you please add a feature to submit_order that allows you to add notes. This would be helpful in tracking and logging trades.

Example:
api.submit_order(symbol, qty, side,type=type, time_in_force=time_in_force, limit_price=None, stop_price=None, client_order_id=None, note = 'this could be a note, so I know why the trade was executed')

This is what client_order_id is for. It's how you can track an order with your own custom UUID.
