[EPIC] Deploy jupyterhub-home-nfs to NASA VEDA production

[yuvipanda]

Once #4647 is complete, we should roll it out to the NASA VEDA production instance. We do not intend to roll this feature out retroactively to other communities unless asked.

What to set the quota to?

To avoid co-ordination overhead, let's set it to 10% + whatever is the current largest single user's home directory usage.

Timeline

There are 2 factors Sarah is balancing when deciding a timeline:

1. Most of the underlying technical work was completed as part of [EPIC] [DevelopmentSeed partnership] Integrate jupyterhub-home-nfs helm chart into 2i2c infrastructure #4647 so this should "just" be turning things on
2. We will be migrating the prod home directories so we expect there to be a greater volume of data, and a lower tolerance to data loss/corruption

Considering these 2 factors, Sarah believes a timeline of 2 weeks is ample.

Once this is complete, the configuration option should also be added to the configurator form here: https://docs.google.com/forms/d/1Gx3v-KaruL6K9VanuwatKEr3qOLJi8ezrcsvGDtZDEQ/edit

FYI, I don't seem to have access to that form. I'm not sure if it's because the link is opening with my personal Google account authenticated first so I'm not being picked up as belonging to the org, or if something else funky is going on with permissions. There is unhelpfully no option for me to change user, and no authuser= showing up in the URL for me to manipulate to force it to see my 2i2c account. So as things presently stand, someone else will have to do the form updating, when the time is right.

ETA: I have been able to access it through an incognito browser and logging in with my 2i2c account. So it must be something funky regarding which Google account the link is picking up.

@sgibson91 I've just invited you as an editor, you should now have full control of the form.
