make this library independent of osio constraints

[hrishin]

In order to make this library work across any OpenShift cluster need to address the following issues:

• build, deploy env:
  build and depoy takes env as target envionment(namspaces) to execute the workload. ATM it takes partial namespace names like stage, run and internally it resolves to osio based namespaces. To fix this issue it should take complete namespace name or envionment details like cluster + namespace.

cd {
    // processing openshift template present in .openshiftio/application.yaml
    def resources = processTemplate(params: [
          RELEASE_VERSION: "1.0.${env.BUILD_NUMBER}"
    ])

    // performs an s2i build
    build resources: resources, env: environment(type:'build')
    // deploy to stage environment
    deploy resources: resources, env: environment(type:'stage')
    // wait for user to approve the promotion to "run" environment
    deploy resources: resources, env: environment(type:'run'), approval: 'manual'
  }

This is one the possible way, pipeline can become independent. Where envionment API resolving complete name space.
