I think golang can check the contents in the struct (we only have int and string in APIServer)?

Prior to this change, only updates to the configuration of exporters (sinks) were handled gracefully, without requiring a FlowAggregator restart. After this change, we also support updating recordContents.podLabels at runtime. For all other unsupported config changes, we print an error log, asking users to restart the FlowAggregator.

This is a partial revert of antrea-io#6378. We cannot easily support live updates to recordContents.podLabels, as it requires re-creating the IPFIXExporter, so that a new IPFIX template set can be sent. Signed-off-by: Antonin Bas <[email protected]>
