Update git submodules

* Update docs/submodules/integration.git from branch 'master'
  to 216bd6a4870c680555d586f0010a633d5fa15700
  - Import Vagrant environment from test/security/k8s

    Infrastructure mockup has been previously set up for CIS guidelines
    checking. Empty Kubernetes cluster was sufficient for that purpose. It
    will be adjusted to satisfy minimal ONAP requirements and should
    eventually supersede previous testing environment.
