moduleapi: Add module:once() to execute a function after module load/startup It is a common pattern for modules to do something like check for prosody.start_time, and execute code immediately if it is present, or wait for the server-started event if it isn't yet. For example, this allows you to run code after all other modules/hosts have been loaded, that are going to be loaded. Such code can now be replaced with a simple call to this method.
