nano instructions

[aaronmarkham]

Description

This PR adds instructions on how to setup MXNet on a Jetson Nano.

I had a previous PR, #14855, that also added the Nano to CI, but this is stuck. So, I'm decoupling the working instructions from the failing CI part.

@lebeg @larroy @KellenSunderland - please review this version. Hopefully we can at least get the instructions published and worry about testing MXNet on the Nano later.

LGTM thanks!

@KellenSunderland @lebeg Can you take a look at this PR?

Looks great

So there's still one issue that needs to be resolved. The pip wheel I have mentioned in the guide doesn't have the write .so file in it. I tried to swap it out with the one that works from the build from source route, but ran into other issues. So I'm sort of stuck. Can anyone help update that wheel? I don't want to publish this guide without that wheel working out of the box. Or I need to remove that option from this guide.

Let's look at this next week ?

@larroy - I have some working wheels now which are now in the guide. The other PR related to this I'll close, but we really need to get CI going and hopefully automate the generation of wheels for this arch. Right now we only have 1.4.0 wheels... but that's better than nothing!

@aaronmarkham The instructions do not render correctly for me here: http://mxnet.incubator.apache.org/versions/master/install/install-jetson.html
