The SummaryRecord.add_value() method is extended to record the data of
MindExplain.

fix get loss error when it not a scalar and fix process specified data
failed when the action is False, and collect_specified_data parameter is
not None

Has fixed collecting optimizer error when mode is eval

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.

add some unittest for summary operator

support ScalarSummary to record number type
