Code Actions in LSP mode

[alanz]

In other IDE's I have used (emacs lsp-mode, vscode), the code action request is sent continuously, much like the highlights request is now in lem. The results are then presented unobtrusively, as a clickable lightbulb in the gutter for vs code, or clickable text on the right hand margin for emacs lsp-mode.

What would be the best way to present available code actions in lem, so that

• it unobtrusively indicates to the user that they exist for the current cursor position
• the user can choose and apply one of them if they choose to.
