v1.2.2

[NEW] Filter only mode

You may choose to operate Logproxy in Filter only mode. It will listen
for messages on the logdrain endpoints, run these through any active
filter plugins and then discard instead of delivering them to HSDP logging.
This is useful if you are using plugins for real-time processing only.
To enable filter only mode set LOGPROXY_DELIVERY to none
