1. collect the origin network in model, and set it to cb_params
2. collect the origin network name in SummaryCollector
3. Update the SummaryCollector API Doc

I added a SummaryCollector to help users automatically collect information
such as the network, loss, learning rate and so on, making it easier to collect this information.

It also can collect train lineage and eval lineage information which is
collected by TrainLineage Callback and EvalLineage Callback in
MindInsight.

I also add some UT for SummaryCollect to keep the code correct.
