There is many way to create droplet.
It will be useful to disable mail notification for creation.
We have two use cases :
> Droplet is created by our action
> An action automatically trigger create a droplet (for example, adding a droplet behind a load balancer because a monitoring system ask it).
For the first case, it could be useful to disable email notification (as we already know that we are creating a droplet).
But I think (email) notification should be the default behavior.
