+ all: use ModuleSupervisor init all auto-start modules.

The new ModuleSupervisor implementation will make use of
special configuration keys under the `kamon.modules` section
to detect all the available modules in the classpath and do
two things with that info:
  1. Log the AspectJ Weaver missing error if any of the
     available modules requires AspectJ.
  2. Start all available modules that are marked with the
     auto-start setting.
