The reliability on agent in GetWorkload()/GetWorkloads()

[jasonjoo2010]

Let's focus on the publish property of a workload.

Generally the network info would be available only after agent detects and saves it into the store. So it won't be available if the agent hung.

But in CreateWorkload/ReplaceWorkload we could find that it's more like a realtime property:

			// inspect real meta
			var workloadInfo *enginetypes.VirtualizationInfo
			workloadInfo, err = workload.Inspect(ctx) // 补充静态元数据
			if err != nil {
				return errors.WithStack(err)
			}

			// update meta
			if workloadInfo.Networks != nil {
				msg.Publish = utils.MakePublishInfo(workloadInfo.Networks, opts.Entrypoint.Publish)
			}

And I remember in the previous implementations the returned structure of GetContainer() has such thing like inspect data enabling the users to do similar thing.
So is it possible to do similar thing in GetWorkload like CreateWorkload?
