Add exclusions to Maven plugin
This commit adds an `exclusions` parameter to the Maven plugin, which can be used to exclude dependencies from the compile classpath of native image. It can be used to remove some dependencies from compilation, such as these injected by Spring Boot for development. Note, however, that if the main jar is configured to have the manifest with `addClaspath` to true, then the manifest file will still reference the jar, and native compile will issue a warning (because the jar will be missing from classpath). Fixes #612
