DEVOPS-2030 Skip Cloudflare at Nersc

[bio-boris]

Description of PR purpose/changes

ee2 was changed to send requests and avoid cloudflare, so send them on the internal network
The internal network is not accessible at nersc, so we have to send through cloudflare
These changes/hack modify the job runner to replace that URL when it is running at NERSC to the public URL
These changes are current deployed on production. You can run a hipmer job to prove it and see that they now run.
Corresponding changes in jobRunner are also deployed on production. kbase/JobRunner#87
