Adds first neovim config for several years

I copied ThePrimeagen setting up neovim based on his repository at
https://github.com/ThePrimeagen/init.lua. The video itself is at
https://www.youtube.com/watch?v=w7i4amO_zaE.

I tried following each step based on the video, but I for some reason
autocomplete did not work properly after a while. So I cloned his repo
and adapted it to some extent to make it more in line with what I need.
This is an early state, but autocomplete works. There is much to do to
mirror my vimrc, if I am going to go down that route.
