This reverts commit ff185a9ae738afac3b0264f61bde6c6b7f72e7c4.

* revert some changes in example code

* update config

* re-blacken python code

* temporarily disable date and diff_py_file

* skip a format

* use yapf to format all python file

* yapf exclude two unittests file for they rely on writing and reading file, and format will break them

* disable diff_py_file because too many diff files cause command following failed

* parameter_server_optimizer support auto_strategy

add lars to fleet meta optimizer

* add auto parallel L1 implementation
test=develop

* fix api document

* consider the combination of different strategies to work together

* add check approval
test=develop

* move paddle.fleet to paddle.distributed.fleet

add lamb to fleet meta optimizer

* refine strategy compiler and meta optimizers
make async as a_sync

refactor fleet api under paddle.fleet
update DistributedStrategy
