Splits capacity commitment to two commitments of the same plan and commitmentEndTime.
A common use case is to enable downgrading commitments.
For example, in order to downgrade from 10000 slots to 8000, you might split a 10000 capacity commitment into commitments of 2000 and 8000. Then, you delete the first one after the commitment end time passes.
