Description

Fuzzing forks

• Used forks in python fuzzing: now we can go back to previous annotation with history having.
• Current strategy: try to go back to the best annotations per 12 attempts.
• Current results (number of executions per second) is not worse then previous version on examples.
• Suitable case: samples/controlflow/conditions.py. Here we can set a big timeout and cover all branches through returning to the previous annotations.

Execution counter

• Added cli argument --execution-counter to save a number of executions. It can be helpful if you need to measure the speed of utbot python
• Added some scripts in samples/testing_utils to collect and show executions information.

Code refactoring

• Small cosmetic changes

How to test
