Login to SciServer directly #1999
Description
I am not a fan of the current approach to SciServer integration as it requires the user to enter his/her SciServer credentials into DeepForge. We should be able to update this to follow the flow used in http://turbulence.idies.jhu.edu/cutout/.
Namely, we should be able to direct the user to SciServer and redirect back to DeepForge on successful authentication.
