jenkins: Add initial jenkinsfile

This Jenkinsfile provides basic CI based on the .travis.yml
which ports the travis behaviour to Jenkins by checking the
following make targets functionallity:

  - make format
  - make lint
  - make vet
  - make cyclomatic-check
  - make test
  - make images
  - make images BUILDER=buildah
  - make demos
  - make demos BUILDER=buildah

The main intention of this commit is to provide an starting point
where anybody can improve the coverage at anytime and get PR cheks
on Jenkins.
