Due to latest rewrite of NSS module, we are doing yajl parsing
ourselves. This means, we had to introduce couple of callback
that yajl calls. According to its documentation, a callback can
cancel parsing if it returns a zero value. Well, we do just that
in the string callback (findLeasesParserString()). If the JSON
file we are parsing contains a key that we are not interested in,
zero is returned meaning stop all parsing. This is not correct,
because the JSON file can contain some other keys which are not
harmful for our address translation (e.g. 'client-id').
