Adding Jenkinsfile for PR pipeline on Fabric8CD infrastructure

[rupalibehera]

Initial commit adding Jenkinsfile for pr pipeline on fabric8CD(http://jenkins.cd.k8s.fabric8.io/job/kubernetes-incubator/)

This PR includes a Jenkinsfile which just does make test for now which will run the tests on every PR and on merge with master.
It uses golang version 1.8.1

The below things are not covered which are there in .travis.yml:

1. It does not test with the Matrix of various versions of go lang.
2. It does not do the coverage
3. It does not sync the docs

@rupalibehera you commit is created with your redhat email. It looks like you don't have that email associated with you github account. You might have to add redhat email to your github account or use the same email that you are using on github for that commit.

[rupalibehera]

Thanks @kadel I just added my redhat email-id to github account, hopefully it works.

CLA has been passed.

@rupalibehera Any way we could test this / authorize this / see what happens? Have you tested this against your Kompose fork?

Let us know!

This saves us having to merge this in, then merge something else, unmerge, etc just to get it test to see if it works.

Code LGTM!

[cdrage]

LGTM

@cdrage , I have tested this against my kompose fork.
Here is the sample successful run : http://pastebin.test.redhat.com/497821
I can tag the experts to review this.
@rawlingsj it would be really great if you can review this PR once :)

I think we could add a check to see if the pipeline is part of a CI or CD. I.e. we dont want to run the release if we are running CI builds on Pull Requests. You could do something like this https://github.com/fabric8io/fabric8-init-tenant/blob/master/Jenkinsfile#L9-L24

[rawlingsj]

Also what this would do is run your CI pipelines for pull requests, it will create a snapshot image and add a comment to the PR once it's available for testing. Like this fabric8-services/fabric8-tenant#125 (comment)

[rupalibehera]

So they just want CI and they are not looking for CD, this pipeline should run on PR and also while the PR is merged to master. Hence I did not explicitly check if it is CI or CD.
@pradeepto and @cdrage could you please confirm this ?

I am not sure if we still add this at least for the snapshot.
@rawlingsj

[cdrage]

@rupalibehera Yeah, we just want CI.

Ok sounds good LGTM
