[WIP] Issue #214 Add basic application deployment testcase

[agajdosi]

This PR adds integration tests via package from the minishift/minishift repository.

The feature file right now tests:

• minishift start
• deployment of several example applications from OpenShift organization
• checks whether OS is really CentOS

I shall probably add more, do we have any often issues with CentOS iso for which I could create a scenario? Any suggestions on what feature should focus?

TODO:

• docs
• feature files
