Collect device statistics

With the variety of device platforms, audio devices, etc., it might be a good idea to collect info like

• device (Raspberry Pi, CHIP, PC, ...) + version
• used device platform (includes Magic Mirror, Hyperion, ...)
• OS (distro + version)
• audio HW
• python version used
• selected voice trigger (pocketsphinx / snowboy / none)
• AlexaPi version

... stuff like this. No private / sensitive info would be collected.

Implement like Home Assistant (it's a good reference project for anything) - generate anonymous UUIDs. This would be on by default with the option to disable it in the config.

This would help us:

• know what features to prioritize and optimize (yeah, this sounds like marketing crap, I'm not even sure if this is true)
• figuring out what config defaults are the best to cover most uses
• knowing if we can remove py2 support in the future
• deciding to add support for a distro if people use it without official support
• knowing how many active AlexaPi instances are actually out there
• and we could have awesome graphs!
