Integration tests: provide a cdk instance that tests running in jenkins can use

We dont have a dedicated OS instance for the integration tests.
Currently the best approach is to have a local CDK since console.engint.openshift.com takes about 2x the time to execute these.
Automatically installing the CDK in jenkins isnt possible since nested virtualization isnt possible: https://engineering.redhat.com/rt/Ticket/Display.html?id=410151
