Remove Digicert CAA records from most domains
Open, In Progress, LowPublic

Description

We received a Digicert certificate approval request from an frtech employee for wikimedia.org, which caused us to want to review our usage of digicert CAA records. CAA works at the subdomain level so we can set the records for payments.wikimedia.org to allow them their issuance while removing the unnecessary records for the rest of the stack.

wikimediafoundation.org should just have LE, wikimedia.org should be left alone (for now...), but all the others in the dns repo should have digicert removed (just LE + pki.goog)

CAA works at the subdomain level so we can set the records for payments.wikimedia.org to allow them their issuance while removing the unnecessary records for the rest of the stack.

So payments is a CNAME and hence we can't add a CAA record for it. That leaves us with the option of either removing the CNAME, or just having fr-tech switch to pki.goog as we have done in production, but that's a longer conversation.

Can we not add a CAA record to the CNAME targets (payments-eqiad/codfw)?

We can yeah but I am not sure if there is something in the fr-tech setup that complicates that. @Jgreen can comment on those bits.
