connectors-ci: hanging step block pipeline completion

[alafanechere]

Under certain scenario a pipeline Step can hang infinitely. This will block the completion of a CI pipeline that will eventually timeout without providing the results of the other step.

Real life example:
The source-file python package install is hanging infinitely due to a pip dependency resolution problem. It makes the nightly build hang:
airbyte-ci connectors --name=source-file test

Solution

Instore a per Step max duration, cancel run_with_completion when the max duration is reached and return a failed StepResult.
