Title: Add source/target options to DNS filter

* Solves LOGSTASH-1489
* Doesn't close it, as the options have to be removed in a later version. This will be another pull request
* Deprecate resolve, reverse and action options

I've tested and versified both the old and new functionality. Comments for the options have been changed to reflect the changes in configuration
