Remove response headers

Emissary can remove a list of HTTP headers that would be sent to the client in the response (e.g. default x-envoy-upstream-service-time).

The remove_response_headers attribute

The remove_response_headers attribute takes a list of keys used to match to the header.

remove_request_headers can be set either in a Mapping or using ambassador Module defaults.

Mapping example

---
apiVersion: getambassador.io/v3alpha1
kind:  Mapping
metadata:
  name:  quote-backend
spec:
  prefix: /backend/
  remove_response_headers:
  - x-envoy-upstream-service-time
  service: quote

will drop the header with key x-envoy-upstream-service-time.

apiVersion: getambassador.io/v3alpha1
kind: Module
metadata:
  name: ambassador
spec:
  config:
    defaults:
      httpmapping:
        remove_response_headers:
        - x-envoy-upstream-service-time
---
apiVersion: getambassador.io/v3alpha1
kind:  Mapping
metadata:
  name:  quote-backend1
spec:
  prefix: /backend1/
  service: quote
---
apiVersion: getambassador.io/v3alpha1
kind:  Mapping
metadata:
  name:  quote-backend2
spec:
  prefix: /backend2/
  service: quote

This is the same as the mapping example, but the headers will be removed for both mappings.
