add Dockerfile and docker-compose.yml to run example code (#635)
* add optional server url arg to http client example

Signed-off-by: Andrew Hsu <xuzuan@gmail.com>

* add Dockerfile to build example http images

Multi-stage Dockerfile with targets for building example http server and
client.

  $ docker build --tag the-server --target example-http-server .
  $ docker build --tag the-client --target example-http-client .

* add docker-compose.yml file for running examples

This docker compose configuration file will help a new user to compile
and run the example code quickly. Uses the Dockerfile to build images
with compiled examples.

  $ docker-compose build http-server http-client
  $ docker-compose up http-server http-client

* add Dockerfile target to build zipkin client

For building the example zipkin client:

  $ docker build --tag zipkin-client --target example-zipkin-client .

* add docker compose service to run zipkin examples

Services to run the zipkin client along with a zipkin collector:

  $ docker-compose build zipkin-client
  $ docker-compose up zipkin-collector zipkin-client

Since the zipkin collector takes a few seconds before it is ready to
receive traces, I added a simple retry loop to the client command.

The collector service exposes port 9411 so user can visit
http//localhost:9411/ to see the trace sent to the collector. Be sure to
search by the trace id logged by the client.

HTTP Client-Server Example

An HTTP client connects to an HTTP server. They both generate span information to stdout. These instructions expect you have docker-compose installed.

Bring up the http-server and http-client services to run the example:

docker-compose up --detach http-server http-client

The http-client service sends just one HTTP request to http-server and then exits. View the span generated to stdout in the logs:

docker-compose logs http-client

View the span generated by http-server in the logs:

docker-compose logs http-server

Shut down the services when you are finished with the example:

docker-compose down
