gRPC HTTP/1.1 bridge could map gRPC codes to HTTP response codes

[dmateusp]

gRPC HTTP/1.1 bridge could map gRPC codes to HTTP response codes:

Currently the gRPC HTTP/1.1 bridge sets the HTTP response code to 503 for any non-0 gRPC codes, it would be great to use a sensible mapping to HTTP response codes instead.

Description:

The mapping in the bridge could be changed to set the HTTP response code based on the mapping you can find in the comments of googleapis/google/rpc/code.proto instead of using 503. In our case it would be useful to return these codes for monitoring / logging on our GCP load balancer.
