Some sort of bootstrap debug mode

I was trying to figure out the required structure of the JAR executable and found that even when enabling a logger via a META-INF/services/java.util.logging.LogManager descriptor, there is too long of a period where the NoopModuleLogger is used as the Module.log value in order to debug bootstrap issues like why the java.util.logging.LogManager implementation class cannot be found.

I would like to create some type of dump logging to console bootstrap debug mode flag that sets the Module.log to StreamModuleLogger(System.out) to facilitate debugging bootstrapping issues.

Assign the issue to me and suggest what you might like the flag argument name to be if you don't like -debug and I'll create a pull request for the feature.
