Remove forms-api task from review apps

What problem does this pull request solve?

Trello card: https://trello.com/c/YWJAZ2A9/2499-remove-forms-api-from-review-apps

Forms-runner now makes requests to forms-admin rather than forms-api to get forms. Update the review apps so that the forms-api container is no longer created and forms-runner makes requests to forms-admin rather than forms-api.

We need to also set the ALLOWED_HOST_PATTERNS environment variable for the forms-admin container so that it allows requests from forms-runner to localhost:3000 to make requests to the forms-admin API without authorization being required.

Things to consider when reviewing

• Ensure that you consider the wider context.
• Does it work when run on your machine?
• Is it clear what the code is doing?
• Do the commit messages explain why the changes were made?
• Are there all the unit tests needed?
• Do the end to end tests need updating before these changes will pass?
• Has all relevant documentation been updated?

🎉 A review copy of this PR has been deployed! It is made of up two components

1. A review copy of forms-runner
2. A production copy of forms-admin

Important

Not all of the functionality of forms-runner is present in review apps.
Functionality such as sending emails, file upload, and S3 submission types are
deliberately disabled for the sake of simplifying review apps.

You should use the full dev environment to test the functionality which is disabled here.

It may take 5 minutes or so for the application to be fully deployed and working. If it still isn't ready
after 5 minutes, there may be something wrong with the ECS task. You will need to go to the integration AWS account
to debug, or otherwise ask an infrastructure person.

For the sign in details and more information, see the review apps wiki page.
