Environment variables are used to specify a maximum number of OpenBLAS threads.

In ubuntu(GPU) environment, numpy will use too many threads for computing,
it may affect the start of the summary process.
Notice: At present, the performance of setting the thread to 2 has been tested to be more suitable.
If it is to be adjusted, it is recommended to test according to the scenario first

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

- handle collection for multiple trains
- how many tensors to collect when sunk
- change loglevel for get_learning_rate
- update calculation of `max_file_size`
- fix how collect_tensor_freq counting

- fix writer pool not exit when max_file_size too small
- fix API docs to illustrate `collect_tensor_freq` and `max_file_size`

Add more detail note for SummaryCollector and SummaryRecord,
else if it is used not right, some proplem will be caused.

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.

1. When initing SummaryRecord, if check failed, self._close is not set,
   which leads to 'SummaryRecord' object has no attribute '_closed'
   AttributeError later on.

2. There may be too many processes for handling summary adapting.
