nvim: Extend lsp for nvim lua development 

Added new functionality to lsp: hovering, go-to definition, referencing,
implementations, etc accessible through the usual hotkeys.

Added commands to invoke LspHover and temporarily disable lsp for the
current buffer (is re-enabled on re-entering the buffer, e.g. with
:e<cr>)

Added tjdevries extended lua lsp implementation containing functionality
for the nvim api itself (especially useful for `vim.api`, `vim.fn`).
