Event translator does not fully reload configuration on reloadDaemonConfig event

Description

Steps to reproduce:

0. Configure a translation that's easily triggered and has at least one parameter assignment
1. Turn up Translator logging to DEBUG
2. Send in an event that gets translated by the translation set up in step 0
3. Change the name of the parameter in the assignment set up in step 0
4. Send in a reloadDaemonConfig event with its "daemonName" parameter set to "Translator" (as expected by the ET)
5. Send in the same event as in step 2 and watch translator.log

Expected result: log message indicates that the assignment being made is for the new parameter name as specified in the changes made at step 3 above

Actual result: log message still indicates that the assignment being made is for the OLD parameter name from translation configured in step 0 above.

Viable (but fairly painful) workaround: restart OpenNMS to reload the ET's configuration fully

Acceptance / Success Criteria

None

This behavior is still present in 14.0.3-1, and possibly later releases.

I found the same issue on 1.8.15!

Step to respoduce:

1)I added two translations for interfaceUp and interfaceDown event to translator-configuration.xml:
--------CUT HERE----------- <event-translation-spec uei="uei.opennms.org/nodes/interfaceDown">
<mappings>
<mapping>
<assignment name="uei" type="field" >
<value type="constant" result="uei.opennms.org/translator/nodes/interfaceDown" />
</assignment>
<assignment name="ifDescr" type="parameter">
<value type="sql" result="SELECT snmp.snmpIfDescr FROM snmpInterface snmp WHERE snmp.nodeid = ?::integer AND snmp.ipaddr = ?::varchar" >
<value type="field" name="nodeid" matches=".*" result="${0}" />
<value type="field" name="interface" matches=".*" result="${0}" />
</value>
</assignment>
</mapping>
</mappings>
</event-translation-spec>
<event-translation-spec uei="uei.opennms.org/nodes/interfaceUp">
<mappings>
<mapping>
<assignment name="uei" type="field" >
<value type="constant" result="uei.opennms.org/translator/nodes/interfaceUp" />
</assignment>
<assignment name="ifDescr" type="parameter">
<value type="sql" result="SELECT snmp.snmpIfDescr FROM snmpInterface snmp WHERE snmp.nodeid = ?::integer AND snmp.ipaddr = ?::varchar" >
<value type="field" name="nodeid" matches=".*" result="${0}" />
<value type="field" name="interface" matches=".*" result="${0}" />
</value>
</assignment>
</mapping>
</mappings>
</event-translation-spec>
--------CUT HERE-----------
2) Then I send the reload daemon config
send-event.pl uei.opennms.org/internal/reloadDaemonConfig --parm 'daemonName Translator'

3) Send an interfaceDownEvent using send-event:
send-event.pl --nodeid 511 --interface 169.254.231.10 uei.opennms.org/nodes/interfaceDown

4) Expected behaviuor, the translator is able to translate the sent event

5) Here is the log message:

Clearly the translator is able to listen for new events but it has not reloaded the related translation-specification.
