Description

Currently, in IMRU testing for fault tolerant, we on purposely fail (maxRetryNumber -1) times, only make last retry successful without injected failure.
We would like to add one more parameter to set numberOfAllowedFailure. For example, if maxRetryNumber is 6, numberOfAllowedFailure is 2, we would only inject failure in the first two runs, and let rest of the retries either successful or naturally get failures from the environment. This would help us to test more scenarios.
