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

Update license header to standard format for source files missed prior.
Add license header to new source files.
Add Makefile check to test all `*.go` and `*.sh` files have a copyright
notice (or comment about them being auto-generated) within the first few
lines.
* Add zipkin exporter
The zipkin exporter implements the SpanBatcher interface. It follows
the current-at-the-time-of-writing document about conversion from
OpenTelemetry span data to Zipkin spans. Which means that endpoint
information is not yet filled.
* Fix typo in docs
* Add a zipkin example
This sends span information to a locally running zipkin collector.
Currently I have a problem getting the collector to show me the spans
after accepting them with HTTP 202. Not sure if this is because of
missing endpoint information.
* Make gitignore consistent
The fixed paths should be prefixed with a slash. The "relative" paths
mean that git will ignore all the files that end with the path.
* Add tests for zipkin exporter
