Introducing ec2-instance-selector

When provisioning a spot fleet, getting the correct instance type can be a little bit overwhelming, log in to the console, look for instance capacity, etc

That's why AWS provides us a really useful tool from the cli, ec2-instance-selector (https://github.com/aws/amazon-ec2-instance-selector)

This makes our lives much easier. You just need to run the command passing resource criteria like vcpus, network performance, ram, etc.

Be sure to have your AWS credentials loaded when you run it.
