Coverage: Diff Checker Bot

[mitche50]

When enabling the unclaimed rewards, an incorrect variable was used causing the bot to double count unclaimed rewards, over allocating funds. This was evident in the distribution rate being higher after enabling this feature, but was missed while auditing the release.

The rewards team should create a bot that runs each cycle and compares the distribution rates by comparing new_cycle_diff[token] / length_of_new_cycle to old_cycle_diff[token] / length_of_old_cycle

If these rates are outside of some defined margin (say 2% +-) then alert the team to this difference for investigation.
