POC - Rolling Time Periods + Decay Two Period

[bonedaddy]

notes:

• code was modified to add decay two period ability to rate limits, and add unit tests for decay two period logic however actual rate limits haven't been migrated to use decay two period
• reason behind this is that actual integration requires significant refactoring to the rate limit functions / workflow

Can you write some docs explaining this mechanism?

From skimming the code it seems to be similar to transmutter pools where the change capacity is bounded by the moving average of past capacity. Is the advantage here making the limit changes smoother?
