Provide an easy to upgrade NSolid versions

[RafaelGSS]

According to https://docs.nodesource.com/docs/nsolid/quickstart/local, nsolid is installed and updated via

$ sudo apt-get install nsolid -y

This, however, isn't a really easy approach as users don't get used to doing it using Node.js. In my opinion, we have two ways of solving it:

• Include nsolid to nvm, volta and other Node.js version managers
• Include a nsolid --update that automatically updates the binary via command line.

What do you folks think about it? @brycebaril @edsadr @trevnorris @santigimeno

Would love to have this at some point. We used to have one for n IIRC but in the end there are a lot of them out there. We need to figure out the priority here and hear from the community what runtime managers they prefer.

I think having it available via nvm would be great, I'm almost sure other package managers would just follow it
