Thanks Joe. 

I think we should have the test prove that a CNAME pointing at this
name is also cleaned up, as well as a value in a multi-valued SRV
record.

A unit test (which I should have written in the first place) for
remove_dns_references covering all the things it cleans up would also
be very helpful.

Thanks!
