Write proposals about crash testing improvement - Part 1

This ticket should cover following ideas:

• Crash test API for the test suites (C++, csuite, Python)
• Fail point for crash testing (e.g., can we certain hooks we can add in our code and let caller know we have reached here)
• Continuous testing - create tests than work on a large real-life db (>100 GB, multiple tables) and do crash and validation
