This is the branch to set up the new install method with Terraform, working on the multiple issues listed in #3397.

Looks good so far 👍

After testing, three more things to be added:

• The cli.yaml file isn't updated with the url for the loadBalancer and the airy status and airy config apply cannot be used
• The output should be in line with the output from the previous installation
• The AWS docs should be cleaned-up for the --provider-config customization parameters (will be added later).

Resolves #3275. This commit was added because the status command didn't work properly.
