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

clean clang format errors and cpplint errors

add some test cases for histogram summary operator
