Fix: Correct time-based delay calculation in metric test loop

- Replaced incorrect float-based timing logic with proper use of Go's time package.
- Previously, delay was calculated using math.Pow() on raw float values, causing unintended near-zero delays.
- Now uses time.Duration arithmetic with jitter and random factor to generate appropriate sleep intervals.
- Also fixed logging statement with incorrect parameter count.
