Update ec2 info and add script to regenerate

[wllgrnt]

Motivation and Context

The EC2 dictionary was out of date, so I pulled a new list of instance types from a third-party website

How Has This Been Tested?

Wrote a script comparing the new and old dictionary versions - some of the old keys no longer exist but otherwise all values match (except one cost being wrong by one cent) .

@wllgrnt how about instead of embedding the JSON output of your script into the python code, we just load it? This will make updating it easier. The caveat is that when you call createOrUpdateService for the AwsBooterService, you need to pass extensions=(".py", ".json")

@braxtonmckee what's your preference?
