AsyncExecutor (#14627) 

* AsyncExecutor: C++ side

* Google naming conventions

* Rename MultiExecutor to AsyncExecutor

* pybind with async_executor

* Naming convention

* remove some flags and unused code

* add refactored file of async_executor and data_feed

* clear async executor interface and add data feed factory

* split async executor into executor_thread_worker and async_executor, refactor pybind, add datafeed and corresponding proto

* Fix async_executor interfaces: 1) Remove all protobufs; 2) Stop after each epoch

* refine async_executor_refactor.cc

* add some files about datafeed

* Revert "add some files about datafeed"

This reverts commit 8ee8133ab841196925a2812b76f18d2812a6701d.

* Interface rework

* add MultiSlotDataFeed

* Creating DataFeedDesc from .proto file, then manipulate it (add/del fields etc) from python side

* update data_feed for add MultiSlotDataFeed

* update datafeed and async_executor to run bow_net demo

* fix bug that finish_set_filelist failed in multithread

* delete finish_binding_memory_(flag), because it can not be marked under the current interface

* Fix bug

* update async_executor.py for support set_use_slots

* update async_executor.py for support set_use_slots and set set_dense_slots

* fix bug that when the number of files is less than the number of threads, it will fetch nan

* remove redundant code, and make executor exit when set a illegal queue size

* add batch_size check

* add MultiSlotDesc

* Revert "add MultiSlotDesc"

This reverts commit 2e72ebfad364ed6b5dcc75f38ffb2a1fdec83d8e.

"""
An asynchronous Executor in Python. Through exploiting the power of
multi-core processor and data queueing, AsyncExecutor makes data reading
and cosuming decoupled, each run in multiple threads in parallel.
Instead of reading data in python side, AsyncExecutor accepts a training
file list, which will be retrieved in C++, then training inputs will be
read, parsed and fed to training network within C++ code.
AsyncExecutor is in active development and the API might change in the near
future.
Example:
>>> data_feed = fluid.DataFeedDesc('data.proto')
>>> startup_program = fluid.default_startup_program()
>>> main_program = fluid.default_main_program()
>>> filelist = ["train_data/part-%d" % i for i in range(100)]
>>> thread_num = len(filelist) / 4
>>>
>>> place = fluid.CPUPlace()
>>> async_executor = fluid.AsyncExecutor(place)
>>>
>>> async_executor.run_startup_program(startup_program)
>>>
>>> epoch = 10
>>> for i in range(epoch):
>>> async_executor.run(main_program,
>>> data_feed,
>>> filelist,
>>> thread_num,
>>> [acc],
>>> debug=False)
Args:
place(fluid.CPUPlace|None): indicate the executor run on which device.
Only CPUPlace supported
Note:
For debugging complicated network in parallel-GPUs, you can test it
on the executor. They has the exactly same arguments, and expected
the same results.
Note: Only running on CPUPlace supported.

Run program by this AsyncExecutor. Training dataset will be in filelist.
Users can also inspect certain variables by naming them in parameter

AsyncExecutor doesn't return fetched variables, instead, it will dump
the values of each fetched variable to stdandard output.
Running the dataset will be on multiple threads, within each a thread
local scope will be created, then all OPs also created in that scope.
Parameters are updated by all the OPs simultaneously.
Args:
program(Program): the program that need to run, if not provied,

data_feed(DataFeedDesc): A DataFeedDesc object
filelist(str): a file containing the training dataset file list
thread_num(int): number of concurrent training threads. See
:code:`Note` for how to set this properly
fetch(str|list): the var name or a list of var names to inspect
debug(bool): When set to True, fetch vars will be printed to
standard output after each minibatch
Note:
the executor will run all operators in the program but not only
the operators dependent by the fetch_list.
Note:
Running AsyncExecutor will be on multiple threads, each bound to a
CPU core. To achieve best performance, it's suggested to set thread
num to be equal or slightly less than that of CPU cores.

Datafeed descriptor, describing input training data format. This class is
currently only used for AsyncExecutor (See comments for class AsyncExecutor
for a brief introduction)
DataFeedDesc shall be initialized from a valid protobuf message from disk:
>>> data_feed = fluid.DataFeedDesc('data.proto')
See :code:`paddle/fluid/framework/data_feed.proto` for message definition.
A typical message might look like:
>>> name: "MultiSlotDataFeed"
>>> batch_size: 2
>>> multi_slot_desc {
>>> slots {
>>> name: "words"
>>> type: "uint64"
>>> is_dense: false

However, users usually shouldn't care about the message format; instead,
they are encouragd to use :code:`Data Generator` as a tool to generate a
valid data description, in the process of converting their raw log files to
training files acceptable to AsyncExecutor.
DataFeedDesc can also be changed during runtime. Once you got familiar with
what each field mean, you can modify it to better suit your need. E.g.:
>>> data_feed.set_batch_size(128)
>>> data_feed.set_dense_slots('wd') # The slot named 'wd' will be dense
>>> data_feed.set_use_slots('wd') # The slot named 'wd' will be used
