The function name getZoneName() was misspelled in the reference.
If the wrong name is used as it was documented, that lead to nasty,
silent failure of the script as lua assumed default behavior of
non-existing functions and doesn't abort.
The object has following methods available:
- ``DNSName getQName()`` - name to update
-- ``DNSName getZonename()`` - zone name
+- ``DNSName getZoneName()`` - zone name
- ``int getQType()`` - record type, it can be 255(ANY) for delete.
- ``ComboAddress getLocal()`` - local socket address
- ``ComboAddress getRemote()`` - remote socket address
