Feature Request: daily backups

[mkellerman]

Have an option to backup settings to iCloud/OneDrive. This should also add the option to auto export the debug logs as well.

We us our log files to analyze and make setting suggestions. Having those auto exported at the end of the day could help create some automated recommendations.

Or is there a way to pull the logs remotely? Or push them to nightscout? I'm leaving the implementation details to the devs.

Thanks for all your help!
