Update configuration docs for Repeat interval (#3552) 

Although it is true that Repeat interval should be greater than or
equal to the Group interval, it should also be a multiple of it too.
If the Repeat interval is not a multiple, then because of how aggregation
groups are flushed, it will be made into one implicitly. This commit
documents this behavior.
