Is your feature request related to a problem? Please describe.
Today CapacityReservationGroup allows creating capacity reservations that can be used only in the subscription where the reservation is created. This new sharing feature would allow a Capacity Reservation Group to be shared across subscriptions.

Describe the solution you'd like
SharingProfile is a new optional parameter introduced in CapacityReservationGroup that contains list of Subscription resource Ids that the CapacityReservationGroup can be shared with. When a Capacity reservation group is created with a sharing profile, the capacity reservation group is shared with all the subscriptions listed in the sharing profile parameter.
