Description

Added new CachedFeedback which we can filter and do not collect to executions but save to limitManager.

Now when we get OutOfMemoryError we will stop process and render generated tests.

Also added a new counter in limitManager for fuzzed objects with FakeNode-s

Fixes #1928

How to test

Manual tests

For methods without arguments (exclude self) in empty class we can fuzz only one execution. Now we should to save only one execution and use memory only for one execution.

Try to generate tests with a large timeout:

class Dummy:
    def propagate(self):
        return [self, self]

Expected: one successfully generated test without memory error
