OptionalackHow redelivery is decided. 'explicit' (the only no-loss/no-dup choice, and the default)
requires each message to be acked; un-acked messages are redelivered after ackWaitMs.
OptionalackHow long the server waits for an ack before a delivered-but-un-acked message becomes redeliverable, in milliseconds; defaults to 30000ms. Lower it to resume faster after a drop.
OptionaldeliverWhere a brand-new consumer starts: 'all' (default), 'new', or 'last'.
