Auto merge of #3573 - Vlad-Shcherbina:map_clone_caveat, r=flip1995
Document map_clone known problems #498 (cherry picked from commit ada0d2c54831a904a53ff4106e0ebb6a0f06a687) This was lost in relicensing (057243f16b4f4233). However, I [acknowledged](https://github.com/rust-lang/rust-clippy/issues/3099#issuecomment-416482309) relicensing so this cherry pick should be fine I guess.
