To enable consistent hashing for a backend:
`nginx.ingress.kubernetes.io/upstream-hash-by`: the nginx variable, text value or any combination thereof to use for consistent hashing. For example `nginx.ingress.kubernetes.io/upstream-hash-by: "$request_uri"` to consistently hash upstream requests by the current request URI.
`nginx.ingress.kubernetes.io/upstream-hash-by`: the nginx variable, text value or any combination thereof to use for consistent hashing. For example: `nginx.ingress.kubernetes.io/upstream-hash-by: "$request_uri"` or `nginx.ingress.kubernetes.io/upstream-hash-by: "$request_uri$host"` or `nginx.ingress.kubernetes.io/upstream-hash-by: "${request_uri}-text-value"` to consistently hash upstream requests by the current request URI.
"subset" hashing can be enabled setting `nginx.ingress.kubernetes.io/upstream-hash-by-subset`: "true". This maps requests to subset of nodes instead of a single one. `upstream-hash-by-subset-size` determines the size of each subset (default 3).
