java allows to set an authority CallOption, but Golang does not

[Ivansamara109]

Hello.

We use gRPC in a service mesh in which our applications connect insecurely to a sidecar on the local network and the sidecar does the work of initiating TLS to backends and load balancing/routing based on the :authority pseudo header.

We use this java grpc implementation feature in our java application. It allows us to re-use a single Channel for multiple services, even if those services are hosted on different domain names.

Is it possible to add the same feature for go implementation of gRPC?
