Turn off oxygen's udp2log instance, move 5xx error log to erbium, turn off some erbium filters
This leaves erbium (and analytics1026) as the only operational webrequest udp2log instances.
oxygen will be used as a kafkatee node, and sampled, and 5xx logs will be moved there.
Once that is done, sampled and 5xx filters will be removed from oxygen, and then
I will work with Jeff to disable fundraising filters too.
