Test the NESE-disk Globus configuration in production

[landreev]

Unlike the NESE-tape setup, where we have one prod. user (OMAMA), the similar NESE-disk storage allocation they created for us has not been tested just yet. Since we have one potential depositor for this service as well, we need to verify that it's actually working.
There is every reason to expect that it will just work (at least as well as the tape version that is), since the 2 setups are largely identical. Everything that needed to be done on the NESE side should be done (storage allocated, Globus roles and permissions etc. created). But, it's just something we haven't done yet, so needs to be confirmed for the fact before we let any users start uploading stuff.

Both upload and download need to be tested.

Also, it would definitely help to deploy 6.4 first, since it contains the improvements made specifically to make long-running Globus uploads more reliable. But that is ready to go as well.
