CapacityReservations/ Capacity Blocks for ML(GPU) in AWS to get allocation/ significant discounts.

Describe the solution you'd like
[A clear and concise description of what you want to happen.]

By using capacity blocks for ML, one can obtain a significant discount compared to on-demand GPU instances. However, we can also use CapacityReservations to allocate additional on-demand instances to the cluster in case of poor availability of on-demand instances.

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]
If the user uses the on-demand CapacityReservationId to the cluster if the reservation expires the cluster falls into normal on-demand instances. But for the Capacity Blocks, the instances will start deleted as these are GPU instances which need to be allocated to other users.
