request help: Does route supports to match ':authority' header of grpc?

[seans2s]

Issue description

I designed different prefix paths for different upstreams of grpc:
/path1/helloworld.Greeter/SayHello --> upstream1
/path2/helloworld.Greeter/SayHello --> upstream2

but grpc-client does not support path prefix:
grpc/grpc#14900
In above grpc issue, they recommend to use ':authority' header.
Can you give me some hint to do this using apisix?

Environment

• apisix version (cmd: apisix version): 1.3
• OS:centos, docker

@nic-chen please take a look

I think path prefix works well in APISIX.

BUT the entire path will be passed to the backend service, like /path1/helloworld.Greeter/SayHello, so the backend service can handle it.

Maybe we could use proxy-rewrite to pass the right path /helloworld.Greeter/SayHello to backend.
