docstring: Get the number of instances set for a version of a module.
  
  This function does not work on automatically-scaled modules.
  
  @param string $module The name of the module to retrieve the count for. If
  null then the count for the current module will be retrieved.
  
  @param string $version The version of the module to retrieve the count for.
  If null then the count for the version of the current instance will be
  retrieved.
  
  @return integer The number of instances set for the current module
  version.
  
  @throws \InvalidArgumentException If $module or $version is not a string.
  @throws ModulesException if the given combination of $module and $version
  is invalid.
