Web server that receives gzip'd POST requests and saves them uncompressed locally

To force Firefox to send a Telemetry payload to this server:

1. Start the server: ./gzipServer.py (you may need to install simplejson Python module)
2. Change the toolkit.telemetry.server Firefox pref in about:config to http://127.0.0.1/
3. Restart Firefox to have Telemetry pick up the above pref change
4. Open about:telemetry (it has the Telemetry namespaces nicely set up) and open the DevTools console
5. Paste the following into the console: TelemetrySession.testPing();
6. The script will save the request it receives to report1.json in the script's working directory

Note: The procedure above will create a "test ping", which is equivalent to a regular Telemetry saved-session ping.

Alternatives:

1. If you just need to see the Telemetry measurements from the current session, you can see them directly on the about:telemetry page in Firefox.
2. If you need to see what the full ping looks like, but you don't need to send it to a server, simply exit Firefox and you will find the ping for the latest session saved in <profile-directory>\saved-telemetry-pings.
3. You can also get the full ping from the DevTools console by opening the about:telemetry page and running the command ping = TelemetrySession.getPayload(). If you need Telemetry from the content process in the ping as well, call TelemetrySession.requestChildPayloads() before you call TelemetrySession.getPayload().
