Support deep_merge_options with 'deeper' merge_behavior 
Support deep_merge_options with 'deeper' merge_behavior 

The `deep_merge_options` parameter should be respected when `merge_behavior => 'deeper'`, especially since 'deeper' is really the only useful of the two non-native behavior options (see https://docs.puppet.com/hiera/3.2/configuring.html#mergebehavior).
