satellite hackfest support for aws deployments

[pseguel-redhat]

Is your feature request related to a problem? Please describe.
I've been triying to deploy the satellite-hackfest on aws with no luck.
On the other hand, I see only instructions for OSP deployments.

Currently I just get to this part:

TASK [infra-ec2-template-generate : Detect all possible Availability Zones that can host all the instance types and pick one] ***
Monday 05 July 2021  09:14:51 -0400 (0:00:00.039)       0:00:15.180 ***********
fatal: [localhost]: FAILED! =>
  msg: |-
    The conditional check 'instances | length > 0' failed. The error was: error while evaluating conditional (instances | length > 0): 'instances' is undefined

    The error appears to be in '/Users/pseguel/Desktop/Ansible_Tests/satellite-demo/agnosticd/ansible/roles-infra/infra-ec2-template-generate/tasks/main.yml': line 4, column 3, but may
    be elsewhere in the file depending on the exact syntax problem.

    The offending line appears to be:

    # that can host all instance types. That results in random errors.
    - when:
      ^ here

Describe the solution you'd like
I'd like to deploy satellite-hackfest on a AWS environment.

Describe alternatives you've considered
I modified a satellite-hackfest-vars.yml with my own values and using cloud_provider: ec2

I also tried using a satellite-infra config on AWS (no luck yet, but just started trying), but the hackfest has satellite 6.9 and a more complete scenario.
