Tree view feature mimicking issue 371 from vim-ls

[lanza]

This is from lsp-mode and ccls. Somebody requested similar functionality from vim-lsp a few months ago and some of the guys working on it have started working on similar functionality. (here and here). I think this would be a fantastic feature to add to coc.nvim.

Have you seen vista.vim?

Not sure since I do not use it, but I think vista.vim does not support call/inheritance hierarchies.

Limited to ccls, the vim-ccls plugin works on top of coc.nvim, and should provide a call hierarchy view that should be similar to lsp-mode/emacs-ccls. However, note that ccls uses a non-standard method for call hierarchies, that is not part of the LSP API.

There is an open issue in Microsoft LSP to add a textDocument/callHierarchy method. I think it would be nice if coc.nvim could add support for this method in the future, even though I am not sure it is currently implemented by any language server.

Sounds similiar as #1649
