Remove all data from previous year (including from cleanup store) after final year end wiki update

[fsvreddit]

• Grab each month from previous year
• Fully delete sorted sets from userPostCountKey/userCommentCountKey

Either:

• Grab all users from the same keys for the current month, and get their current scores from the cleanup log
• Delete the cleanup log entirely
• Repopulate the cleanup log using those values

Or:

• Delete everything from the cleanup log where the next check time is less than daysbetween-1
