Terminate contract by ident

This operation has been deprecated and will be removed in the future!
Please refer to our "API Lifecycle Management" and our "API Migration Guide" to find out more.

DEPRECATED: Use '/contracts/{contractIdent}/actions/terminate' or '/contracts/{contractIdent}/actions/terminate-extraordinarily' instead. A contract's termination can be done by setting a new end date that is usually smaller than the previous set contract end date. If no end date is set, the end of the current billing interval will be chosen as the next termination date.
