Feature discussion: instance discovery

[jnmoal]

I'm using terraform and its workspace to allow deploying multiple times the exact same environnement. This imply to use different host name for each environnement. Those instances are basically on-demand, and won't last more than 8 hours.

The access to those instances is done through bastillion. For now, I juste pre-register the instance name so that project can have access to it. And when the environnement is not needed, I unregister them.

That's why, I would love to use some kind of instance discovery based on EC2 tags, so that instance are automatically discovered by bastillion and made available for users.

What do you think of that?

Thanks.
