[martin-mat]

Describe the bug In case that the cnf setup is unsuccessful on issues like:

• cluster-tools not ready after waiting for it (180)
• deployment of the cnf returns an error
• deployment of cnf not ready after waiting for it (180) spec test ignore it and continue in test execution

see #2081

Expected behavior Spec test will fail as soon as mentioned errors occur
