Cancel cooperatively

[Catrya]

A user can cancel an active order, but will need the counterparty to agree.

To initiates a cooperative cancellation the user have to send a message to Mostro with the action cancel and Mostro responds back with a message with the action: "cooperative-cancel-initiated-by-you"

Also Mostro will send a message to the user's counterparty with the action: "cooperative-cancel-initiated-by-peer" and if they accept the cooperative cancellation they must send Mostro a message with the action "cancel"

Then Mostro will send a message to both parties informing that their order was canceled cooperatively.
