Use `LspProgressUpdate` event instead of hooking `vim.lsp.handlers["$/progress"]` directly, as discussed in #51. I'm not using `vim.lsp.util.get_progress_messages()`, because it doesn't return token, and it's actually private for now, maybe not ready...
As described #9
I'm using `.clang-format` file, schemas provided by [yamlls](https://github.com/redhat-developer/yaml-language-server), and I have to add schemas manually. Is it possible to support yaml? Thans a lot!
