For small scale testing, add additional gws to rdr, this is to test small scale load balancing. having 2 gateways might lead to instabilities (load ping-pong or fallback to single gw in case the other is loaded). The gateways are from different generations to evaluate impact on each. gws are kept within the xrootd/webdav aliases to evaluate the impact of cross-alias requests and for quick rollback capability. VOs/VO reps switch a part of the transfers to the rdr aliasAtlas sends some transfer to rdr
