module_loader, web_framework: Update console log messages

- Drop message for initialization of each app. This was removed earlier but was
reintroduced during init() refactoring. There is not much use for these messages
and the noise they generate hide some important messages relating to domains
added.

- Print lists in a better way for humans.

- Add a log message after all the initialization is completed.
