Dependency issues, new versions of googleapis are no longer compatible

[jimmyff]

Hope everything is going okay over there. I have started getting dependency issues with aqueduct:

Because googleapis_auth >=1.0.0 depends on crypto ^3.0.0 and aqueduct 4.0.0-b1 depends on crypto ^2.0.6, googleapis_auth >=1.0.0 is incompatible with aqueduct 4.0.0-b1

I guess this comes under the same ticket as #919 but I opened a new one as this is more specific.
