reverseproxy: Improve hostByHashing distribution (#5229)
* If upstreams are all using same host but with different ports ie: foobar:4001 foobar:4002 foobar:4003 ... Because fnv-1a has not a good enough avalanche effect Then the hostByHashing result is not well balanced over all upstreams As last byte FNV input tend to affect few bits, the idea is to change the concatenation order between the key and the upstream strings So the upstream last byte have more impact on hash diffusion
