Quickfix for elided_lifetimes_in_paths warning

[IndianBoy42]

1. hidden lifetime parameters in types are deprecated
   `#[warn(elided_lifetimes_in_paths)]` implied by `#[warn(rust_2018_idioms)]` [elided_lifetimes_in_paths]
2. indicate the anonymous lifetime: `<'_>` [elided_lifetimes_in_paths]

I see the hint as part of the diagnostics but there is no code action to automatically add that. I also have a keybinding defined to instantly apply a code action with the quickfix kind according to the lsp protocol so it would be best if this assist was a quickfix.
