Misleading log message when service does not exists

[pehala]

If you specify a service that doesn't exists, the WASM will report it like this:
2022-12-14T11:49:33.745044Z error envoy wasm wasm log: (root/2) 2078290764: failed to initiate fetch of configuration data for 65: failed to dispatch HTTP (https) call to cluster outbound|443||<authority> with authority <authority>: BadArgument
The actual system endpoint will return 404 and not 400 as would the error message suggest.
