Samantha ffad58009e grpc: Backend discovery improvements (#6394) ... - Fork the default `dns` resolver from `go-grpc` to add backend discovery via DNS SRV resource records. - Add new fields for SRV based discovery to `cmd.GRPCClientConfig` - Add new (optional) field `DNSAuthority` for specifying custom DNS server to `cmd.GRPCClientConfig` - Add a utility method to `cmd.GRPCClientConfig` to simplify target URI and host construction. With three schemes and `DNSAuthority` it makes more sense to handle all of this parsing and construction outside of the RPC client constructor. Resolves #6111		2022-09-23 13:11:59 -07:00
