Add/remove Some() or Ok() or Err() wrapper

[adamchalmers]

I frequently find myself refactoring code and needing to either add or remove a Some() wrapper from an expression. Similar need for Ok() and Err(). It'd be great if Rust Analyzer had an action to add or remove these wrappers.

I can approximate this somewhat with macros of key sequences in my editor, but it'd be neat if RA could do it :)

In some cases we offer these as diagnostic quick fixes:

let x: Option<i32>  = 42; // Wrap in Some
let x: i32 = Some(42); // no Unwrap available

let x: Result<i32, ()>  = 42; // Wrap in Ok
let x: i32 = Ok(42); // No Unwrap available

Given that, I'm not sure we need another assist.

I'll look into adding an equivalent unwrap fix to that diagnostic
