Title: removing port setting

We don't need to do this via the buildpack, it can be set like any other jvm arg using the Gradle run script convention of using <APP_NAME>_OPTS

So, the following manifest file will work for my app called example-books and all the mapping between jvm args and env vars are consistently done in the same place.
```
