### dnsrecord-mod: allow to modify ttl without passing the record
The command `ipa dnsrecord-mod <zone> <record> --ttl ` requires to provide at
least one record to modify. When none is specified, it prompts by proposing each of the
existing records, for instance:
```
$ ipa dnsrecord-mod ZZZZZ.org ns11 --ttl=86400
No option to modify specific record provided.
Current DNS record contents:

A record: xxx.xxx.xxx.xxx
AAAA record: xxxx:xx

Modify A record 'xxxx.xxxx.xxxx.xxxx'? Yes/No (default No):
Modify AAAA record 'xxxx:xx'? Yes/No (default No):
ipa: ERROR: No options to modify a specific record provided.
```
The admin should be able to modify the TTL value without re-entering the record
information. The issue happens because of an internal check that forgot to consider
'dnsttl' as a valid standalone modification.

Fixes: https://pagure.io/freeipa/issue/7982

### XMLRPC tests: add new test for ipa dsnrecord-mod $ZONE $RECORD --ttl
    
The test suite did not have any test for modification of the TTL of an existing DNS
record.
