-- Returns the name, Amazon Resource Name (ARN), @NumberOfRules@ and
-- effective dates of all Cost Categories defined in the account. You have
-- the option to use @EffectiveOn@ to return a list of Cost Categories that
-- were active on a specific date. If there is no @EffectiveOn@ specified,
-- you’ll see Cost Categories that are effective on the current date. If
-- Cost Category is still effective, @EffectiveEnd@ is omitted in the
-- response. @ListCostCategoryDefinitions@ supports pagination. The request
-- can have a @MaxResults@ range up to 100.
