get_facts function issue on n3k running 7.x

[seismiccollision]

the 'show environment' command as part of the pycsco/nxos/utils/nxapi_lib.py get_facts function results in unexpected json tags https://github.com/jedelman8/pycsco/blob/master/pycsco/nxos/utils/nxapi_lib.py#L2445

seen in 3 revs of 7.0(3)I2(X)
I don't think I know enough python yet to propose a smart fix but I could give it a shot if it's any help

>>> print json.dumps(result, indent=2)
