Resolve #676

I'd like to request to revert this change. The list is very important to let the user know which deps are shipped into the final shaded jar, especially when deps pull lots of transitive deps. If someone thinks it's noisy, please consider making the log level configurable.

They are configurable. If you want to see this set the log level to debug.

what I mean "configurable" is, allow setting those message level via plugin's configuration, not run mvn command in debug mode.
