headerName property
The name of the HTTP header to match.
For matching against the HTTP request's authority, use a headerMatch with
the header name ":authority". For matching a request's method, use the
headerName ":method". When the URL map is bound to a target gRPC proxy
that has the validateForProxyless field set to true, only non-binary
user-specified custom metadata and the content-type header are
supported. The following transport-level headers cannot be used in header
matching rules: :authority, :method, :path, :scheme, user-agent,
accept-encoding, content-encoding, grpc-accept-encoding,
grpc-encoding, grpc-previous-rpc-attempts, grpc-tags-bin,
grpc-timeout and grpc-trace-bin.
