Describe the feature

Provide LSP messages and progress when formatting buffers.

Provide background

I'm using none-ls (ex null-ls) for formatting, and whenever I format my files I get a nice message in my statusline which I find really helpful since I want to know what my LSP/linter/formatter is doing in the background, and when.
I tried to migrate my formatting from none-ls to conform, and this is where I got stuck.
This is how my statusline fetches the LSP messages and progress, which is similar to the way I've seen other plugins do it.

cannot use this plugin without it

Additional details

I filled the significance above based on my requirements, since I don't want to lose my LSP messages during formating from my statusline 😅
