add new Folding@home Rock-on using the linuxserver.io docker image. Fixes #219

[phillxnet]

Includes:

• root.json addition.
• Nvidia env hard wired for simplicity in anticipation of future GPU capabilities within the Rock-on system via a newer docker subsystem.

Fixes #219

@FroggyFlox Ready for review.
Note that I have slight concerns about the use of the '@' char in the root.json file. Easier for us to test post pull request submission however.

General information on project

This pull request proposes to add a new rock-on for the following project:

• name: Folding@home
• website: https://foldingathome.org/
• description: "...distributed computing project for simulating protein dynamics, including the process of protein folding and the movements of proteins implicated in a variety of diseases." quoted from their about page. This project is of recognised scientific import and depends on community members volunteering part of their CPU / GPU hardware resources.

Information on docker image

• docker image: https://hub.docker.com/r/linuxserver/foldingathome
• is an official docker image available for this project?: I couldn't find one, however linuxserver.io are a trusted supplier and often offer UID & GID capabilities over and above many official docker images and their offering for this project was updated 4 days ago.

Checklist

• Passes JSONlint validation
• Entry added to root.json in alphabetical order (for new rock-on only)
• "description" object lists and links to the docker image used
• "description" object provides information on the image's particularities (advantage over another existing rock-on for the same project, for instance)
• "website" object links to project's main website

Testing:

• Stopping and Starting works as expected and successfully resumes an ongoing FAH ‘Work Unit’.
• Turning off, Un-installing, and then Re-installing with the same share also successfully resumes the FAH ‘Work Unit’.
• After a Rockstor system reboot the Rock-on also successfully resumed the current FAH ‘Work Unit’.
• N.B. the optional FAHControl app was note tested, and neither was wiping the entry of this optional port selection (i.e. establishing if it was actually optional within the Rock-on framework).

The docker image was noted to be around 220 MB installed:

leap15-1:~ # docker image list

@FroggyFlox I have now done an end-to-end test of the repo with this pr pre-merged and the result hosted locally. A Leap15-2 beta based Rockstor instance, reconfigured to use this local repo, then worked as expected with the resulting Rock-on.

A further concern re:

Note that I have slight concerns about the use of the '@' char ...

I think we are OK on this front as when I checked the function of our emergency delete-rockon script all looks to also function as expected; bar the Python version warnings (See: "move to python 3" issue rockstor/rockstor-core#1877):

Thanks @phillxnet !
It does seem like you've tested it rather well and given I'm unlikely to have time to test and review it quickly, do not wait for me if you want to.

I'm sorry for the trouble, but these times are very very busy for me unfortunately.

[phillxnet]

@FroggyFlox Thanks and no worries. I think I'll take the plunge then :).
