Hm, that may be a valid use-case. We should discuss how we want the DNS
record modification to behave.

The proposed API is not what we want, since we can modify multiple
attributes at once, e.g.:

ipa dnsrecord-mod DNSZONE DNSRECORD --a-rec=10.0.0.1 --aaaa-rec=::1

I can introduce new option --old-<DNS_TYPE>-rec for each DNS record type
available, e.g. --old-a-rec, --old-aaaa-rec, --old-srv-rec etc. You
would be able to do:

ipa dnsrecord-mod DNSZONE DNSRECORD --old-a-rec=10.10.2.3
--a-rec=10.11.12.13

This would of course increase the size of this patch. I tried to find
how we treat other multi-value LDAP attributes. In most cases the
behavior is the same like in my first patch (user mail, mobile...) or
the modification is not supported at all (list of privilege
permissions).
