Support setting authToken to use a token for upload rather than username/password. This is "based" on Id0c47d088d6e8febbae3c96caecc81ebe247754e which does the same for pypi. There we run a test by uploading to the test pypi server, I'm not aware of a similar thing for npm. Change-Id: Ie8610bdfaa33b2120a61802c12e6ba534fe55464
