Begin the process of migrating away from the "strongly encouraged not to use"[0] Ec2 spot fleet API to the more modern `ec2:CreateFleet`. Unfortuantely the `instant` type fleet does not guarantee fulfillment with either on-demand or spot types. We'll need to add a feature similar to `wait_for_fulfillment` on the `spot_fleet_request` resource[1] to `ec2_fleet` before we can rely on it. We also update the existing target fleets to support provisioning generic targets. This has allowed us to remove our usage of `terraform-enos-aws-consul` and replace it with a smaller `backend_consul` module in-repo. We also remove `terraform-enos-aws-infra` and replace it with two smaller in-repo modules `ec2_info` and `create_vpc`. This has allowed us to simplify the vpc resources we use for each scneario, which in turn allows us to not rely on flaky resources. As part of this refactor we've also made it possible to provision targets using different distro versions.

Flatten the networking to a single route on the default route table and a single subnet. * enos/ec2_info: add a new module to give us useful ec2 information including AMI id's for various arch/distro/version combinations. * enos/ci: update service user role to allow for managing ec2 fleets.
