Notify parent ClientConn to re-resolve in grpclb (#1699) 
The parent ClientConn should re-resolve when grpclb loses connection to the
remote balancer.

When the ClientConn inside grpclb gets a TransientFailure, it calls
lbManualResolver.ResolveNow(), which calls parent ClientConn's ResolveNow, and
eventually results in re-resolve happening in parent ClientConn's resolver (DNS
for example).

This PR adds a method to balancer.ClientConn interface, so balancer can tell
parent ClientConn to re-resolve.

gRPC-Go

Build Status GoDoc GoReportCard

The Go implementation of gRPC: A high performance, open source, general RPC framework that puts mobile and HTTP/2 first. For more information see the gRPC Quick Start: Go guide.

Installation

To install this package, you need to install Go and setup your Go workspace on your computer. The simplest way to install the library is to run:

$ go get -u google.golang.org/grpc

Prerequisites

This requires Go 1.6 or later. Go 1.7 will be required as of the next gRPC-Go release (1.8).

Constraints

The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the list, you need a discussion with gRPC-Go authors and consultants.

Documentation

See API documentation for package and API descriptions and find examples in the examples directory.

Performance

See the current benchmarks for some of the languages supported in this dashboard.
