modulemanager: Allow modules to expose module.ready - to be called after init
This is a shortcut for module:on_ready() which exposes the functionality in an
idiomatic way consistent with module.load, module.unload, etc.
module.ready runs when the module is loaded and the server has finished
starting up.
