springboot Expose additional CNB builder options with build plugins

The CNB builder infrastructure supports the options cleanCache and verboseLogging, which control builder behavior. The Maven and Gradle plugins should expose these options to the user and pass them to the builder.

BootBuildImage in the Gradle plugin already has properties for cleanCache and verboseLogging and applies them to the BuildRequest:

Image in the Maven plugin, which is used by BuildImageMojo has the same functionality:

As far as I can tell, this has already been implemented. @scottfrederick please re-open this if I've misunderstood.
