Feature Targeting for Istio 1.6+, using envoy filter (WASM)

1. install Istio 1.6 to a cluster (see readme)

2. install the echo-service pod (see readme)

3. test that you get a response (without feature header injection):

   curl --resolve echo.localhost:80:127.0.0.1 -vvv http://echo.localhost

4. ensure you have the wasm target added (rustup target add wasm32-unknown-unknown).

5. build the filter and copy it to /tmp/envoy-filters, so that it will be mounted in the sidecar container:

   cd ../../../adapter-proxy-wasm
   make build-image
   mkdir -p /tmp/envoy-filters
   cp feature_targeting.wasm /tmp/envoy-filters

6. deploy the EnvoyFilter resource to the cluster:

   make

7. test that you get a response (with default feature header injection):

   curl --resolve echo.localhost:80:127.0.0.1 -vvv http://echo.localhost
