change syslog and snmptrap default settings

I have a longstanding ticket in progress on simply handling Cisco router and switch logs (which do not work due to undocumented message format requirements), but yep, I gave up.  It is just not an area LM is focused on.  I moved my log handling to SumoLogic and place collectors on the same boxes I have LM collectors on, hence my question here.  I still want to relay information from SumoLogic into LM, but it will be strictly metric-based data based on API queries to SumoLogic.  Still working on that...
