Feature: add dynamic interval support.

Dynamic Interval

Add a dynamic interval feature that automatically adjusts the time between pod terminations based on the number of candidate pods in your cluster. This helps ensure appropriate chaos levels in both small and large environments.

How it works

With dynamic interval enabled, chaoskube will calculate the interval between pod terminations using the following formula:

interval = totalWorkingMinutes / (podCount  * factor)

Where:

• totalWorkingMinutes = 10 days * 8 hours * 60 minutes = 4800 minutes (we assume that all pods should be killed during 2 work weeks)
• factor is the configurable dynamic interval factor

The dynamic interval factor lets you control the aggressiveness of the terminations:

• With factor = 1.0: Standard interval calculation
• With factor > 1.0: More aggressive terminations (shorter intervals)
• With factor < 1.0: Less aggressive terminations (longer intervals)

Example scenarios

• Small cluster (100 pods, factor 1.0): interval = 48 minutes
• Small cluster (100 pods, factor 1.5): interval = 32 minutes
• Small cluster (100 pods, factor 2.0): interval = 24 minutes
• Large cluster (1500 pods, factor 1.0): interval = 3 minutes
