changed my mind, import distutils.version

I don't think any of our system imports use "from x import y"

Perhaps we should log the attributes here? (Minus the login credentials.)

As-is, if a bot uses a remote-device-file (and they will), it will be very hard
for a user to see how it's configured.

It may be helpful to be able to select on OEM (I think it's 'brand' in the
json).
