Subject: [PATCH] Make MQTT property value publicly accessible (#10577)

Motivation:

There was no way to read MQTT properties outside of `io.netty.handler.codec.mqtt` package

Modification:

Expose `MqttProperties.MqttProperty` fields `value` and `propertyId` via public methods

Result:

It's possible to read MQTT properties now
