Hello. After upgrade from v1.15.1 to v1.15.3 we have seen a number of the below errors in the fluentd logs:

2021-10-05 13:35:33 +0000 [error]: Failed to reload config file: expected end of line at systemd.conf line 8,12
  7:   @id in_systemd_kubelet
  8:   matches [{ "_SYSTEMD_UNIT": "kubelet.service" }]

This error was root caused as an issue with the splunkhec plugin. I think KFO should completely remove Splunk support for now by removing splunk-hec and splunkhec plugins until these tickets below are fixed:
splunk/fluent-plugin-splunk-hec#187
fluent/fluentd#3530 or cmeerbeek/fluent-plugin-splunkhec#27

Issue splunk/fluent-plugin-splunk-hec#187 has been fixed with release v1.2.10. Would it be possible to remove the deprecation for this plugin and include it again?

Hello. Sure we can work on it!

That would be great!

BTW, I've built my own image based on the latest KFO image, in which I re-added the 1.2.10 release of the plugin. Everything is working, config reload is not causing any trouble.
