[Bug] MQTT 5: max payload size response

[dmytro-landiak]

Describe the bug

When the MQTT 5 client is connecting, the wrong Maximum Packet Size is returned. Based on the code, the min value between tcp and ssl listeners is returned:

Math.min(tcpMaxPayloadSize, sslMaxPayloadSize)).

In this way, if the ssl communication is used and tcp has lower value, then this lower value is returned for ssl but it should be greater.

The correct behavior is when the single max payload size can be set for all listeners or separate ones for each of them.
