[Feature Request]: Exclude specific services from CDN

[gidsg]

Describe your idea/feature/enhancement

It would be useful if services could be selectively excluded from the CDN/domain integration (where this has been enabled at app level). This would be useful where the custom domain/DNS is not required for the service and the load balancer or apprunner AWS provided hostname is sufficient

(This is currently a pain point for us as we need to go to another team to alter DNS to provision these hostnames, even when it is not required for the service)

i.e. if a service was excluded, there would be no attempt to create an ACM certificate and a custom domain alias will not be set.

Proposal

This could be defined during svc init e.g. svc init --exclude-from-cdn would disable the CDN/domain automatic integration for that service.
