fix(dist_utils): fix port conflict in setup_distribution

[gyt1145028706]

如果端口冲突，则寻找一个未被占用的端口并修改 os.environ["MASTER_PORT"]

[KaiLv69]

这样每个rank可能因为先后顺序，导致获得的master_port不一样。可以像torchrun一样直接报错终止程序，并提示用户修改环境变量。

用bind会出现 将可用的端口判为不可用的情况

比如按照提示export了新的端口 但是下一次用的时候还会检测到port used 为False 改为connect就没这个问题

为什么这里从bind改成了connect?

export环境变量本身并不会占用端口，s.connect在这里用不合适吧，你可以看看connect和bind的区别
