enos: use on-demand targets (#21459)
Add an updated `target_ec2_instances` module that is capable of
dynamically splitting target instances over subnet/az's that are
compatible with the AMI architecture and the associated instance type
for the architecture. Use the `target_ec2_instances` module where
necessary. Ensure that `raft` storage scenarios don't provision
unnecessary infrastructure with a new `target_ec2_shim` module.

After a lot of trial, the state of Ec2 spot instance capacity, their
associated APIs, and current support for different fleet types in AWS
Terraform provider, have proven to make using spot instances for
scenario targets too unreliable.

The current state of each method:
* `target_ec2_fleet`: unusable due to the fact that the `instant` type
  does not guarantee fulfillment of either `spot` or `on-demand`
  instance request types. The module does support both `on-demand` and
  `spot` request types and is capable of bidding across a maximum of
  four availability zones, which makes it an attractive choice if the
  `instant` type would always fulfill requests. Perhaps a `request` type
  with `wait_for_fulfillment` option like `aws_spot_fleet_request` would
  make it more viable for future consideration.
* `target_ec2_spot_fleet`: more reliable if bidding for target instances
  that have capacity in the chosen zone. Issues in the AWS provider
  prevent us from bidding across multiple zones succesfully. Over the
  last 2-3 months target capacity for the instance types we'd prefer to
  use has dropped dramatically and the price is near-or-at on-demand.
  The volatility for nearly no cost savings means we should put this
  option on the shelf for now.
* `target_ec2_instances`: the most reliable method we've got. It is now
  capable of automatically determing which subnets and availability
  zones to provision targets in and has been updated to be usable for
  both Vault and Consul targets. By default we use the cheapest medium
  instance types that we've found are reliable to test vault.

* Update .gitignore
* enos/modules/create_vpc: create a subnet for every availability zone
* enos/modules/target_ec2_fleet: bid across the maximum of four
  availability zones for targets
* enos/modules/target_ec2_spot_fleet: attempt to make the spot fleet bid
  across more availability zones for targets
* enos/modules/target_ec2_instances: create module to use
  ec2:RunInstances for scenario targets
* enos/modules/target_ec2_shim: create shim module to satisfy the
  target module interface
* enos/scenarios: use target_ec2_shim for backend targets on raft
  storage scenarios
* enos/modules/az_finder: remove unsed module

[QT-572][VAULT-17391] enos: use ec2 fleets for consul storage scenarios (#21400)
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.

[1] https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/spot_fleet_request#wait_for_fulfillment

* enos/consul: add `backend_consul` module that accepts target hosts.
* enos/target_ec2_spot_fleet: add support for consul networking.
* enos/target_ec2_spot_fleet: add support for customizing cluster tag
  key.
* enos/scenarios: create `target_ec2_fleet` which uses a more modern
  `ec2_fleet` API.
* enos/create_vpc: replace `terraform-enos-aws-infra` with smaller and
  simplified version. 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.
