Tune intergration tests workflow

[akuzminsky]

• Match max line size in yaml files with pylint - everywhere 120 characters.
• It looks the "if" condition didn't work. I suspect the ">" didn't produce a single line. Tested with pyyaml.
• Don't pause a test bc it won't work in GHA anyway - a step must fail in order to start an SSH session.
