Added processId in the response for delete all contacts from a list.
You will now receive a processId along with total (backward compatible) in response schema when you pass the parameter "all": true in Delete a contact from a list endpoint.
This is because a process will be created which will handle this task asynchronously.
You can check the status of the process using the processId in the get process API.
