Feature request: Support enableTaskIDBasedBlobDigest for preheat job in Manager. Now client.download_task gRPC API has supported enableTaskIDBasedBlobDigest, refer to https://github.com/dragonflyoss/api/blob/main/proto/common.proto#L653. Manager REST API needs add enableTaskIDBasedBlobDigest field for preheating job, and set enableTaskIDBasedBlobDigest to call client.download_task gRPC API. For the Manager's REST API, the default value of enableTaskIDBasedBlobDigest should be true, and the frontend Console can set it when creating or querying preheat jobs. Refer to dragonflyoss/client#1499.
