Handle Region Initialization for FedRAMP

[sam-nguyen7]

On non-govcloud account the operator expects there to be a default subnet to be used when creating and terminating ec2 instances. Per https://docs.aws.amazon.com/govcloud-us/latest/UserGuide/govcloud-ec2.html#govcloud-ec2-vpc govcloud accounts may or may not have a default subnet. Therefore, when in govcloud env, AAO needs to create a vpc, one subnet, run the ec2 instance, tear it all down.
