In the end, salt-cloud is just used to retrieve instances details from EC2 API.
You still need to setup a provider in salt for the region where your instances
are launched.

Here is what the reactor does when a minion comes up:

* wait for the new instances to ping the salt master when it receives
a notification from Amazon SNS
* use salt-cloud CloudClient to retrieve instance instance details from EC2 API
* stores the instance-id / minion-name association in a sqlite database
