Implement retry strategy

[testableapple]

Is your feature request related to a problem? Please describe.
Most of the frameworks allow us to retry failed tests. Maestro currently does not. It would be great to have such an option.

Describe the solution you'd like

• Maestro users can set up a retry-tests-count in the config file globally or in some flow in particular (similar to -retry-tests-on-failure flag in XCTest).
• By default, this count should be equal to 0 (if flow fails, then it fails straight away)
• If a user sets it up (e.g.: 3) and the flow fails on the first run, then Maestro automatically starts it from scratch, and so on
• These repetitions are clearly displayed in the logs

Describe alternatives you've considered

This is an essential feature. As the Maestro Cloud docs correctly state:

The behavior of an application can be complex and challenging to verify, leading to unreliable test results in some instances. This can be caused by various factors such as animations, API calls, backend availability, network interruptions, and temporary outages.

We could for sure just restart the whole test suite ourselves if it fails, but that's far less efficient than just rerunning the failing tests. So a built-in mechanism similar to Maestro Cloud would be much appreciated.
