Bug 1565767

Description of problem:

Failed to build jenkins pipeline build from git repo behind http/https proxy.
This case is similar to: https://bugzilla.redhat.com/show_bug.cgi?id=1405952
But, we'are able to see that the FIRST build fails. We can edit the git https proxy of the slave pod and if we run again it succeeds. 

"Per default, the 1st Jenkins build in a project creates a new Jenkins instance/pod in that project (if jenkins service does not exist) from a template, using standard image/configuration. This standard configuration does not contain any proxy definitions nor does the template.
Once the jenkins instance/pod has been setup in the project, one is able to configure a proxy via UI, so that the 2nd and further runs can use it. "

Steps to Reproduce:

Description of problem:
Failed to jenkins pipeline build from git repo on openshift cluster behind http/https proxy

Version-Release number of selected component (if applicable):
openshift v3.4.0.37+3b76456-1
kubernetes v1.4.0+776c994
etcd 3.1.0-rc.0

How reproducible:
Always

Steps to Reproduce:
1.Launch an openshift cluster behind http/https proxy
2.Create a project, create pipeline bc
 $ oc new-app https://raw.githubusercontent.com/openshift/origin/master/examples/jenkins/pipeline/samplepipeline.yaml
3.Edit bc to use git repo source, like below:
"source": {
            "type": "Git",
            "git": {
                "uri": "https://github.com/dongboyan77/jenkins-pipeline-ruby-test"
            }
        },
        "strategy": {
            "type": "JenkinsPipeline",
            "jenkinsPipelineStrategy": {
                "jenkinsfilePath": "jenkins/pipeline/Jenkinsfile"
            }
        },

4.Start a new pipeline build

Actual results:
Pipeline build failed, cannot git clone from git repo

Expected results:
Pipeline build succeed
