Write a decorator rate_limit(max_calls, period) that limits the number of function calls with a sliding window over time: no more than max_calls calls in the last period seconds. If the limit is exceeded, the call should not be executed. Consider that the function can be called from multiple threads. Example: @rate_limit(max_calls=5, period=60) the sixth call within a minute should be rejected.
