+ 1. Prepare an existing generic centos7/fedora27+ VM with VM_IP as a USER with paswordless sudo privileges
+ 2. Install on an existing VM as a USER, enable nested virtualization
+ 3. Start minishift cluster with profile minishift
+ 4. Run Jenkins with metrics enabled
+ 5. Load containers from a user defined as project_repo from joejstuart/contra-demo
+ 6. Load helper containers from CentOS-PaaS-SIG/contra-env-infra
+ 7. Setup Jenkins with a a job DSL seed job and sample jobs from CentOS-PaaS-SIG/contra-env-sample-project
+ 8. Disable the linchpin-executor container
