Feat/payuk firewall rules

[dibyadhar]

📲 What

Adding custom firewall rules that is going to be implemented in a project but using a toggle variable to keep it off form the generic implementation.

There is a issue as discussed here that results in tight coupling of the policy and rule groups for now, which might get remediated in future release.

hashicorp/terraform-provider-aws#28100
hashicorp/terraform-provider-aws#34956

🤔 Why

Add additional tls alert rule.

🛠 How

By using dynamic block and custom toggle variable to configure TLS Alert rule.

👀 Evidence

In Customer PR (i.e in the root module PR) there is an attached build log and aws snapshot for the deployment.

🕵️ How to test

By toggling the variable on in the root module when enabling firewall feature

Why has the PR template been cut short?
It should have th What, How, Why and evidence that things are working when it is deployed.

This is fine for now. It would be good to provide a list of your own custom rules but looks like that isn't possible from what you have said. This PR is just allowing us to turn on/off a custom alert tls rule which is fine.

This is much better thanks, as now we have some control over what is happening.

OK happy with this now
