Suggestions on improving README and .env files

[shawnsp]

These suggestions came from my experience setting up Clowdr:

1. AWS README

   1. In step 4: cp cdk.context.json.example cdk.context.json
   2. AWS Configuration: make XXXX as default values for "clowdr/openShotKeyPairName" and "clowdr/openShotCertificateArn"

2. Realtime README

   1. cp .env.example .env
   2. In services/realtime/.env, uncomment RABBITMQ_USERNAME RABBITMQ_PASSWORD

3. Packetriot Add playout subdomain on: 1. Packetriot account 2. JSON object template on main README

4. Auth 0

   1. order numberring is confusing.
   2. HASURA_URL value needs to be https

5. playout .env Add AWS_CLOUDFORMATION_NOTIFICATIONS_TOPIC_ARN

AWS README

In step 4: cp cdk.context.json.example cdk.context.json
AWS Configuration: make XXXX as default values for "clowdr/openShotKeyPairName" and "clowdr/openShotCertificateArn"

We should be ripping out all references to OpenShot. We don't use it right now and it's highly unlikely that it's coming back.

Realtime README

cp .env.example .env

Yep, fair. Will get round to this at some point or will accept PR.

In services/realtime/.env, uncomment RABBITMQ_USERNAME RABBITMQ_PASSWORD

Same. Though I think it's better to just uncomment them in the .env.example rather than telling the user to do it manually.

Packetriot Add playout subdomain on:

1. Packetriot account

I don't think the actions/realtime service are documented like this in the README either. Looks like we just tell you to use your own domain, which means there's no need to reserve subdomains from Packetriot. I know you have been using Packetriot's domains for your work, but I don't want to just duplicate their documentation. I'd suggest just mentioning this at a high level and linking to their doc pages.

2. JSON object template on main README

Yep, happy to accept a PR there.

Auth 0

order numberring is confusing.
HASURA_URL value needs to be https

Also happy to accept a PR for these.
