Delete old instances of a process model in the ProcessCube. 

## Inputs

: payload.duration (number): The number of given time periods.
: payload.time_type ('hours' | 'days'): The type of time period to use.
: payload.batch_size (number): The number of instances to be deleted simultaneously. (default 100)

## Outputs

: Explanation of the payload:

Object
{
    successfulDeletions: [Array of strings],
    failedDeletions: [Array of objects]
}

- successfulDeletions:
    - Type: Array<String>
    - Content: A list of successfully deleted process instance IDs.

    - excample:
        successfulDeletions: [
        "instanceId1",
        "instanceId2",
        "instanceId3"
       ]

- failedDeletions:
    - Type: Array<Object>
    - Content: A list of objects containing details of the failed deletions.
    - Each object has the following fields:
        - id: The ID of the process instance that could not be deleted.
        - error: The error message or the reason for the error.

- Example of a complete output:
    {
        successfulDeletions: [
            "instanceId1",
            "instanceId2",
            "instanceId3"
        ],
        failedDeletions: [
            { id: "instanceId4", error: "Permission denied" },
            { id: "instanceId5", error: "Instance not found" }
        ]
    }

The node processes the IDs in configurable batches (default value: 100) and inserts successfully deleted or failed instances into the arrays accordingly.
As processing is currently forced to batch, a detailed error output is not possible. 
If an error occurs during the processing of a batch, all Id's of this batch are marked as faulty.
