(rumqttc) setting v5::MqttOptions::set_max_packet_size to None is not effective

[yann-leprovost22]

Instead of accepting any packet size for incoming message, Some(default_max_incoming_size) is used in the network_connect method, leading to a Codec using max_incoming_size = Some(default_max_incoming_size) instead of None.

I would have expected that set_max_packet_size(None) leads to max_incoming_size = None in the Codec.

Changing the default_max_incoming_size override part: #1017

Tested against mosquitto broker only

Do you know what version this originated at? I'm thinking my issue might be related, though I am seeing slightly different behavior in one way or two (my first comment in the linked discussion): #1020
