Logstash Cloud Foundry Filter

Hello everyone,

I've been working on a logstash filter that interfaces with the PaaS platform Cloud Foundry and I would like to have it published in the logstash plugin repo.

Application logs generated in this environment contain a non-static GUID that relates back to an application. This makes it very difficult to determine a logs source when multiple applications are funneling to the same logging endpoint. This filter aims to solve this issue by using the GUID in each log to determine which application it came from.

I've put together a suite of rspec tests and a README at the github link below to better detail out the filter fields and features. As per the logstash filter creation guide the first step was to create an issue here. Any feed back, suggestions, or criticisms are welcomed.

You can find the filter here: https://github.com/ahahtyler/logstash-filter-cloudfoundry
