…ary. (#2596) * A hack to greatly improve load times I was investigating gazebosim/gazebo_test_cases#1576 , in my investigation it came to my notice that `sdf::Element` takes forever to destroy (We should open a ticket somewhere about this). If we are skipping serialization we might as well not create and destroy an SDF Element. This hack greatly speeds up the load time for gazebo.

Summary
I was investigating
gazebosim/gazebo_test_cases#1576 , in my investigation it came to my notice that
sdf::Roottakes a long time to be constructed. While I am submitting changes upstream to reduce the impact of the creation ofsdf::Root, in the event that we don't serialize a model, I'm proposing we just send an empty string accross. This should minimize both network traffic and make load times more manageable.Checklist
