fix(sl): warn ops regarding CAA records

[kishore03109]

Problem

Prevent this from occurring by warning the agency and ops beforehand regarding a possible site launch failure route.

Solution

Check for existence of CAA records, and if found, check if they 'trust' Amazon, else ask them to add DNS records that specifically allow for this.

the assumption we're making here is that if there's only one CAA record, it's the whitelisted amazon one right?

[kishore03109]

not really, the condition to check here is: if it has any CAA record, at least one has to be the amazon one
in the case where there is no CAA record, actually all this is ok already

[seaerchin]

don't we need the else if asAmazonCAAWhitelisted check here?

[kishore03109]

oh my conidtion is wrong i think that caused the confusion ps

[kishore03109]

changed, hopefully this clearer
