capture the image name without building it

Is it possible to have some way to evaluate the image name?

mvn initialize help:evaluate -Dexpression=jib.to.image -q -DforceStdout

Alternatives

parse out the entry from the pom and then evaluate it (typically our image names have parameters)

```
image=$$(xmlstarlet sel -T -t -v "/_:project/_:build/_:plugins/_:plugin/_:configuration/_:to/_:image" pom.xml| sed -e 's/^[ \t]*//' -e 's/[ \t]*$//')

echo "$image" | mvn -N -q -Drevision=$TAG_NAME -DforceStdout help:evaluate
```

Standardise on a parameter for the image name and modify all existing builds and add governence to enfoce it
