Provide ability to list modules which are on deployment's classpath

Expose that via mgmt run-time model, so it gets available in CLI.

Current possibilities:
Currently only debugging of application server can reveal this information and user must have good knowledge about management internals.

Use cases:
When optimizing footprint of an application user can use this list to identify unneeded implicit dependencies and exclude them.

This feature can be used to identify duplicated dependencies delivered via deployed application.
