Describe the Bug

1. endpoints use a multi-IP model like 127.0.0.1:8080;127.0.0.1:8082
2. i use producer to send a message
3. when proxy which ip is 127.0.0.1:8080 crushed, i found message may be send failed.

Steps to Reproduce

1. endpoints use a multi-IP model like 127.0.0.1:8080;127.0.0.1:8082
2. use producer to send a message
3. proxy which ip is 127.0.0.1:8080 crushed, you will found message may be send failed.

What Did You Expect to See?

If one of the proxy addresses becomes unavailable, gRPC can automatically retry using an alternative IP address instead of propagating an error upstream.
Take Java's gRPC as an example. This behavior is natively supported by its built-in failover mechanism.

What Did You See Instead?

golang-sdk don't support the grpc failover mechanism.
