[emacs-berlin] Moving from lsp-mode to eglot

Hey, thanks for sharing your opinion and dotfiles. Currently the only thing I'm
really missing from lsp-mode is an activity indicator when the Rust Language
Server is running (which in Rust can take quite some time...).

There's an experimental add-on for eglot that provides that (among other
additions), leveraging some specific extensions of `rust-analyzer`, the
Rust LSP server:

Let's see how it works :)

cheers
