Update to kernelci prevents provisioning of new box
Issue Background
Various changes have been recently made to kernelci, this causes provisioning to exit with an error.
Issue description
Initially get a storage_certname as undefined, once that is fixed - see the new kernelci-backend install information, other errors are produced, the install needs a second ansible call (like the frontend has). The nginx instance is not listening on port 8888 until the box has been rebooted and then there are nginx install errors.
Acceptance criteria
When vagrant up on a fresh box works without errors.
