With reference to the following guide for sending NXLog output to Splunk using HEC:
https://nxlog.co/documentation/nxlog-user-guide#splunk-hec-collection

The NXLog community edition om_http is missing the add_http_header() procedure:
https://nxlog.co/docs/nxlog-ce/nxlog-reference-manual.html#om_http

This means it is not possible to output nxlog-ce data to http where a header needs to be added to the http post, such as the Splunk HEC:
https://docs.splunk.com/Documentation/Splunk/7.0.3/Data/HECWalkthrough

Is this functionality deliberately missing from the community edition, or can it please be added?
