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