[device] alpha beta profiler

[YuliangLiu0306]

What does this PR do

This PR provide a alpha-beta profiler to profile the alpha and beta value of given device list.

This profiler could be used individually to profile the metrics of communication performance for a cluster, but also could be used in auto-parallel system to give infomation to search the best logical device mesh of the given device list.

Usage:

    >>> physical_devices = [0, 1, 4, 5]
    >>> ab_profiler = AlphaBetaProfiler(physical_devices)
    >>> ab_dict = profiler.profile_ab()
    >>> print(ab_dict)
