Remove request headers
Emissary can remove a list of HTTP headers that would be sent to the upstream from the request.
The remove_request_headers attribute
The remove_request_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_request_headers:
  - authorization
  service: quote
will drop the header with key authorization.
apiVersion: getambassador.io/v3alpha1
kind: Module
metadata:
  name: ambassador
spec:
  config:
    defaults:
      httpmapping:
        remove_request_headers:
        - authorization
---
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.
