Motivation
Modify distributed sampler and keep the manual_seed behavior same with pytorch original version
Refers to open-mmlab/mmdetection#7440, open-mmlab/mmdetection#7432 and open-mmlab/mmagic#815.
Modification
add seed to distributed sampler and apply
g.manual_seed(self.epoch + self.seed)synchronize the seed in init function
