add manual recovery mode to dxf/import #59640
Description
Enhancement
when importing large mount of data using global-sort where one round of import takes a lot of time, we might meet some error that is harder to investigate without the intermediate data in hand, and sometimes the bug might be easy to fixed by a hotfix PR and we can continue the import, it might be more flexible and efficient than retrying the whole task.
so we want to add a ManualRecovery mode to DXF, when some subtask failed, the task will move to awaiting-resolution state, and manual operation is needed for the task to continue.
