This adds a notice about a compatibility issue with diesel and the new feature resolver. This will display a notice if it detects the scenario where diesel causes a build error. It also prints a not when using cargo fix --edition when it detects a setup that may fail.

This fixes diesels problem, but I wonder if there is some way to write those hints in a more general style so that other crates benefit from that warning as well?

- Try using the previous resolver by setting `resolver = \"1\"` in `Cargo.toml`
(see <https://doc.rust-lang.org/cargo/reference/resolver.html#resolver-versions>
for more information).
- Check for the 2.0 release of diesel which does not have this problem.

This warning is only shown if there is an actual error, right? In that case I propose not to have this line here, as there is no 2.0 release yet.
