feat(neovim): adds denite, deoplete, languageclient plugins

This patch adds 3 plugins that IMO improve my developer experiences:

1. denite
2. deoplete
3. languageclient

I mainly use this plugins for JavaScript and Rust development as of now.
Further configuraton will be needed but the current settings also works
fine as of now.  # Please enter the commit message for your changes.
