Support pipeline deployment style

In the web-console jenkins pipelines are supported in the following way:

• when opening up an empty project you get a special template:
  

• which offers 2 different jenkins variants (and a full example that contains app source and build pipeline):
  

• once executed you get a special build type pipeline
  

• the full example template is using the following build config with the strategy type JenkinsPipeline:

  apiVersion: v1
  kind: BuildConfig
  metadata:
    name: sample-pipeline
    namespace: gulu
    selfLink: /oapi/v1/namespaces/gulu/buildconfigs/sample-pipeline

    creationTimestamp: '2017-04-04T15:05:00Z'
    labels:
      app: jenkins-pipeline-example
      name: sample-pipeline
      template: application-template-sample-pipeline
