Log:
  lua: add modules.loaded hook
  
  This may be used for the local module to hook in and load any additional
  modules that it wants, since it can't modify the modules table internal to
  config. We may consider adding API to do so at a later time, but I suspect
  it will be more complicated to use with little return.
  
  status is captured but ignored for the purpose of loading the hook. status
  will be false if *any* module failed to load, but we typically don't let
  that halt the boot so there's no reason to let it halt hooks. Some vendors
  or setups may have expected fails that would be actively thwarted by
  checking it.
  
  We may, at a later date, consider adding an API for letting non-config
  modules check which modules have successfully (or not) loaded in case an
  unexpected failure *should* halt whatever they are doing.
