Not compatible with Graylog2 6.x

[domrcrel]

Graylog2 6.0 seems to use Guice 7 which removed the javax.inject method. See: https://github.com/google/guice/wiki/Guice700

Graylog crashes on startup if this plugin is installed, with the new version.

I experience the same after upgrading to Graylog2 6.0

See attached file for errors in the log.

After I disabled the module Graylog started up again.

I ended up using a lookup table to query for PTR records of the source field then used it in a pipeline rule. It works the same, and even allows you to look at fields other than source.

I don't think this plugin is needed anymore. I just needed to learn. :)
