Update launch_telemetry_server.py with heka config

- Add heka configuration per Bug 920696
- Add production config files for prod and secondary servers
- Use queue-based "process incoming"
- Use binary install for node.js (should be much faster)
Add 'fabric' dependency, allow 'name' override.

The "primary" telemetry server needs fabric to fire up the "telemetry-incoming"
service.

Add an optional parameter to override the EC2 instance name (so we don't have
to create a new config file to launch many servers)
Update provisioning logic and production config.
Add Mozilla Public License
Add standard "started on port bla" message.
Add read/written bytes for compressor.
