Arvados

Integration feature requested by user:

They have an external system that wants to launch a workflow on Arvados. They'd like to be able to link directly to a workflow launch page, and supply the project uuid where the workflow should run.

The URL should be something like /workflow/<uuid>/launch?project_uuid=xyz

or /workflow/<uuid>?action=launch&project_uuid=xyz

This should work even when the user is logged out; they should go through the login process and arrive at the launch page after they have logged in.

If it is not too much additional work, it would be a nice feature to also be able to provide simple workflow parameters in the query string, but the only one thing required by the user was the project uuid.
