Similar for the 2018 edition (bug 1613975) we should prepare geckodriver for the 2021 Rust edition.

James, when is a good time to get started? Is it after the release as estimated in October?

We need to wait for Firefox's rust toolchain to update to a release containing the new edition. I think this is going to end up bumping the minimum supported rust version, which could be a problem for people making custom geckodriver builds, so I don't think we want to rush these changes for no reason. But in general I think our policy is to match Firefox.

Practically, I doubt any of the changes are going to be a significant problem for us, so I imagine we'll just run the update tooling and take any suggestions. There's some chance that we'll want to make manual fixups, but nothing jumps out.

Ok, so lets do it for the 0.32.0 release then.
