lr_cycle_limit

[aivision2020]

in train.py the default value is 1
but when called from /scheduler_factory.py the default value is 0
cycle_limit=getattr(args, 'lr_cycle_limit', 0)
This makes trouble if you use this function not via train.py. it means the default values for this function crash

@aivision2020 does it assert in get_cycle_length fn? 0 was supposed to be equivalent to 1 but I clearly didn't test that. Will fix soon. Tx
