This sets multiple threads in Deckhand's chart config (4) and set workers to just 1. Deckhand's database is not configured to work with multiprocessing. Currently there is a data race on acquiring shared SQLAlchemy engine pooled connection strings when workers > 1. As a workaround, we use multiple threads but only 1 worker.
