Add GoCD support

[cisum-la]

Add GoCD support and add documentation about it to the README

This will be very useful to us as we are using GoCD

[cisum-la]

Is there any documentation around how to add support for a new server type - in my case GoCD
I looked around the code and it appears i need to create a new file GoCD.js in /app/services folder
and add support similar to e.g. jenkins or travis
Do you guys support cctray parsing?

[marcells]

That's exactly the way to do it. Just take a look at the implementations in the service folder.

What is cctray parsing?

[marcells]

Ah, I see. No, currently cctray isn't supported.

A universal cctray service might be a good idea.

If you want you can implement it. Or a specific GoCD service, where we could implement more configuration parameters, if we need to.
