Make distributed fused lamb test names friendly to keyword filtering

[crcrpar]

This is merely cosmetic as the current parametrization creates test case names such as NcclDistributedFusedLAMB.test_distributed_fused_lamb_no_copy_True_opt_kwargs_{'overlap_reductions': False, 'dwu_num_blocks': 1, 'dwu_num_chunks': 1, 'fused_norm': True, 'fuse_scale': True, 'clip_after_ar': False} whic is not ideally friendly to keyword filtering.

it might be worth thinking of removing no_copy check here

apex/apex/contrib/optimizers/distributed_fused_lamb.py

Lines 160 to 166 in f03c6fb

	# Check if collectives have no_copy option
	self._reduce_scatter_no_copy = (
	'no_copy' in inspect.getfullargspec(torch.distributed.reduce_scatter).args

	self._all_gather_no_copy = (
	'no_copy' in inspect.getfullargspec(torch.distributed.all_gather).args
