Bug #43738 SNMP Trap source IP is always 127.0.0.1

Description:
The SNMP trap source IP is always set to 127.0.0.1. 

It would be nice to give the option to set the source IP to the agent's host name or primary IP address, so that hosts can be dealt with individually in the SNMP consumer. 

How to repeat:
o Create SNMP based events across a number of distinct monitored hosts
o Check the source IP for each SNMP trap

Suggested fix:
Allow the option to set the source to the agent IP/host name

This is a duplicate of 41361 which was fixed in the 1.3.3, 2.0.x, and 2.1.x trees.  

I double checked the 2.0.5 and latest trunk builds and the UI field is present.

Please look under Settings/Global Settings/SNMP Traps for a text field with the title "Agent Address (optional)" which allows a user to manually specify a valid hostname or IP address which gets used for the SNMP trap agent address.

This appears related, if not identical, to bug#42703.

fixed in 2.1 release branch

Patch installed in versions => 2.1.0.1019.

verified new changes work as designed in build 2.1.0.1020

An entry has been added to the 2.1.0 changelog:
