Progress specification

[Massolari]

There is this plugin I'm trying to use in Neovim that displays when the language-server is indexing files.
It works with a variety of language servers, like tsserver, rust analyzer, null-ls, haskell, and some others, but it does not with elm-language-server.
In the README it says that the language server needs to implement the progress specification

Expected Behavior

When the language server is indexing files, it should appear in the editor, like:

Current Behavior

Nothing shows up

Possible Solution

Check if we implement this specification and if we do, investigate why the plugin doesn't work

Steps to Reproduce (for bugs)

1. Install the plugin
2. Open an Elm file

Context

In big projects, elm-language-servers takes a while to index all the files, so, it'd be nice if we have some indication of the progress

Your Environment

• Version used: 2.4.1
• Editor used: Neovim 0.6.1
• Environment name and version (e.g. node.js 5.4): Node v17.7.1
• Operating System and version: MacOS 12.3

For vim-lsp, I opened a PR that approaches this issue.

Server side this has been implemented since the initial release I think. So this problem is likely client side.
