Add more workers per meshdb pod

[WillNilges]

I was reading some docs today and I realized that gunicorn could be run with more workers. I've noticed MeshDB can sometimes perform poorly for somebody if somebody else is doing something intensive, so I think this might help us with concurrent requests while a pod is waiting on an IO operation or something (like the DB).
