Describe the bug

When using the addLayer endpoint to add a header layer like:

curl -XPOST -H "Authorization:Bearer {token}" -H "Content-Type: application/json"  -d '{"placement": {"path": "Features.CAMP.DeepHeader.child35", "index": 0}, "layer": {"type": "header", "name": "child351", "sublayers": [], "description": "c"}, "mission": "MSL", "forceClientUpdate": false}'  http://localhost:8889/api/configure/addLayer

"sublayers": [] should be automatically included if it wasn't. Otherwise, subsequent layer adds under that header will not work,

What did you expect?

Adding header layers does should include a 0sublayers array
