Channelz servicer is in charge of
pulling information from C-Core for entire process. It will allow the
server to response to Channelz queries.

The Channelz statistic is enabled by default inside C-Core. Whether the
statistic is enabled or not is isolated from adding Channelz servicer.
That means you can query Channelz info with a Channelz-disabled channel,
and you can add Channelz servicer to a Channelz-disabled server.

The Channelz statistic can be enabled or disabled by channel option
'grpc.enable_channelz'. Set to 1 to enable, set to 0 to disable.

This is an EXPERIMENTAL API.

Args:
    server: A gRPC server to which Channelz service will be added.
