feat: prepare for parallel deployment in new LZ

[marnixdessing]

• Added configuration based on branch name
• Added new way to deploy DNS records to the root hosted zone
• Only deploy current CNAME and DS records when on production branch
• Configured main branch to be used for the new LZ

[marnixdessing]

CloudFormation template diff gecheckt met de configuratie voor de branch production. Er is diff voor alle remote stack custom resources in de account stages (in de DNSSEC stack)

• auth-prod
• acceptance
• test-2
• test-3
• test-4

Diff is de random string waarde die er voor zorgt dat de custom-resource bij elke deployment wordt geupdate:
