Swagger-codegen version

3.0.0

Steps to reproduce

Run ./bin/rust-petstore.sh on 3.0.0

Suggest a fix/enhancement

The command line arguments to swagger-codegen have probably changed with 3.0.0, and they need to be updated in the petstore script to work correctly.

Start with bin/rust-petstore.sh and run it with swagger-codegen 3.0.0 to reproduce the unrecognized -DpackageName argument. Inspect the command-line invocation and update the script's arguments, then rerun the script to confirm the Rust petstore generation completes without the error.
