Cannot process SNMPv3 Informs due to random Engine ID associated with users

Description

A customer has reported a problem on Trapd when receiving SNMPv3 Informs. Upon restarting OpenNMS, Trap stops processing Informs, and the following error appears on the log:

On the source code, a random Engine ID is associated with each USM User defined in trapd-configuration.xml, which is the behavior when an explicit ID is not passed when creating the UsmUser object, and I believe this is the source of the problem.

The problem could affect all Meridian versions as the UsmUser handling dates from 2011, but for now, I've added M2018 and M2019 to the list.
