// Set a customer's state as ACTIVE or SUSPENDED.
// For simplicity, these actions are implemented by updating the
// customer's status. Note that this could be done also using
// @PUT. In general, these actions may involve several steps (a
// workflow) that cannot be easily translated into a single @PUT
// action by the client.
