I considered how to document the behavior of linking with packaged modules vs from run-time image.  For example (1) document in `--list-plugins` output, (2) via Plugin API to indicate whether accumulate with base run-time image or not.

Ultimately, we want to know the jlink command-line options if it's linked with packaged modules.   So I think `--verbose` output would serve as a good documentation.   I'd like to hear other opinions.

This probably need to extend Plugin API to indicate if this plugin will carry forward in linking from the run-time image.
