Changing request route to another backend api doesn't work

[SMakhrov]

Due to no answers in this ticket #149 and at discussion: https://github.com/tetratelabs/proxy-wasm-go-sdk/discussions/148 I had to up this problem again.

Problem definition:
I want to change backend api address from localhost:8099 (web_service) to localhost:8100 (web_service_canary).

What was ​tried:
According to tip from #149 I have tried to use header :authority. But it doesn't work.

My code is presented here:
https://github.com/SMakhrov/proxy-wasm-go-sdk/tree/dev/feature/example_change_authority/examples/change_authority

For run use:

make build.example name=change_authority && make run name=change_authority
curl http://localhost:18000

Please help anyone.

As I sadi, this is more about Envoy configuration rather than SDK nor Proxy-Wasm at all. You'd better learn Envoy basic before dive deeper into Wasm world which is highly advanced field.

Having said that, I added the example in #160 so I could save others like you in the future. Thanks!
