Update documentation to match implementation in envoyproxy/envoy#2440.
Makes the WeightedCluster.total_weight field visible in documentation. Update ClusterWeight.weight and traffic shaping document to match.

Add listener_filter_chain to Listener, which is a list of individual
listener filters that make up the filter chain for sockets accepted
with the listener. These filters are run before any in the
'filter_chains', and these filters have the opportunity to manipulate
and augment the connection metadata that is used in connection filter
chain matching. Order matters as the filters are processed
sequentially right after a socket has been accepted by the listener,
and before a connection is created.
As an example the functionality controlled by Listener options
'use_original_dst' and 'use_proxy_proto' can be implemented as
listener filters instead of being hard-wired into Envoy's listener
logic. This makes also extensions (like proxy protocol v2) easier to
implement and deploy.

* protodoc: make protodoc fast again.
Some low hanging fruit optimizations. This takes address.proto.rst build
from ~21s to ~1.7s.

Created new definitions in api_build_system.bzl that wrap
go_proto_library, go_grpc_library, and go_test. Changed rules in api/BUILD and
test/build/BUILD to use these new definitions. In the future these
definitions could be expanded upon for auto generation in api_proto_library.

Currently clusters can not open both HTTP1.1 and HTTP2 upstream
connections at the same time. When the new cluster option
"auto_http2" is set to "true", the cluster must open an HTTP2 upstream
connection if the downstream connection is HTTP2, and an HTTP1.1
upstream connection if the downstream connection is HTTP1.1. This option
is to have no effect if there is no corresponding downstream
connection.
This functionality removes the need to operate multiple clusters and
routing rules for them when the backends accept both HTTP1.1 and HTTP2
connections, and when the choice of the HTTP protocol is significant,
as with gRPC.

We need to track statistics in a client neutral way, since the Google
gRPC client doesn't have upstream stats. This will allow us to track the
gRPC status returned by the remote (or inferred from events such as
client timeouts).

In support of https://github.com/envoyproxy/envoy/issues/2200 and some
Google internal needs, we are planning on adding support to Envoy to
allow a configuration (or possibly build) driven decision on whether to
using the existing Envoy in-built Grpc::AsyncClient or
the Google C++ gRPC client library (https://grpc.io/grpc/cpp/index.html).
To move in this direction, the idea is we have the xDS ApiConfigSources,
rate limit service config and other filter configurations point at a
GrpcService object. This can be configured to use an Envoy cluster,
where Grpc::AsyncClient will orchestrate communication, or to contain
the config needed to establish a channel in Google C++ gRPC client
library.

This is intended to capture some recent threads, it can grow as we learn
new lessons.
