This should address all the comments I dropped onto pull request #37.
The only significant fix here is that the SSL command line options should all work now, although slightly differently than how they work in the InfluxDB 1.x script. Whether or not SSL is enabled is controlled by the URL, specifically whether it is an https: URL or an http: one, and the options just control the CA cert parameters.
If there was history data collected via the --poll-loops option, but not yet used to compute history stats, do so on script shutdown. This should reduce the amount of data lost when the script restarts, for example to reboot the system on which it runs, since --poll-loops allows for collection of history data beyond the 15-minute buffer size the dish (currently) holds.
This will only work if the script is shut down via SIGTERM or SIGINT (for example, by interrupting with Control-C).
