Gets a list of Length Of Stay discounts for a particular listing. Lengths of Stay are created with thresholds for individual lengths, and apply until the next length threshold is reached.
E.g. if discounts are added for 5 days and 30 days, then during pricing any length between 5 and 30 will be discounted at the 5-day level.
Any length at 30 or above will be discounted at the 30 day level.
Discounts will be applied to both standard and custom nightly pricing.
