Add support for telemetry endpoint

To test:
1. Create a RequestBin - https://requestbin.io/
2. Run code-server with `CS_TELEMETRY_URL` set: 
  i.e. `CS_TELEMETRY_URL="https://requestbin.io/1ebub9z1" ./code-server-<version>-macos-amd64/bin/code-server`
3. Load code-server in browser an do things (i.e. open a file)
4. Refresh RequestBin and you should see logs
