Rename neovim to pynvim

I'm getting this error:

[ncm2_core@yarp] Traceback (most recent call last):

When installing the latest python-client. Solved it by changing the imports. (don't know a lot of python but this seems to solve the issue)

merge it, please

Why?
According to ncm2/ncm2#102 and https://github.com/neovim/pynvim/tree/master/neovim, import neovim still works

@mcchrish You need to remove neovim package and re-install pynvim is needed.
Because the package upgrading doesn't work properly.

Considering that import neovim is still available and pynvim was created 7 days ago. I don't want to break the software for those who install python neovim client using the system package manager, which usually results in older version for point release linux distros.

I should probably merge this PR later.
