This feature will be used by the stream processing offload engine (SPOE) to parse dedicated configuration files without mixing HAProxy sections with SPOE sections. So, here we can back up all sections known by HAProxy, unregister all of them and add new ones, dedicted to the SPOE. Once the SPOE configuration file parsed, we can roll back all changes by restoring HAProxy sections.
