In fabric environment fabric-gateway/gateway-mq profile doesn't support ssl passthrough

Issue

• I'm standing up a cluster of AMQ brokers. But with dynamic ports/hosts, we want a predictable gateway for customers to connect to. We decided to explore using the fabric-gateway, but we just found out that it only supports ssl-offloading; not passthrough. Is there a way to achieve ssl passthrough on the fabric?

1. AMQ Client (SSL) ---------->Gateway-mq (SSL)--------------> AMQ Broker (SSL)
would get an EOF error on the client, whereas

2. AMQ Client (SSL) ---------->Gateway-mq (SSL)--------------> AMQ Broker (Openwire)
would work.   Also,

3. AMQ Client (Openwire) ---------->Gateway-mq (Openwire)--------------> AMQ Broker (Openwire)
would work as well.
