New Backup format for core

[pvizeli]

Proposed change

• Handle core/homeassistant like an add-on with on full feature folder and settings.
• Simplify the code
• Offload our SecureTar into own Module
• Add version handling to handling different backup format in future

It's not a real breaking change but we handle the homeassistant core folder now out of the folder list (but we support still the old format) - You can now not restore the core config without core itself which will also represent the core today and his internal database. People should also stop to use core folder for own configs

Regarding "You can now not restore the core config without core itself which will also represent the core today and his internal database. People should also stop to use core folder for own configs"

Should the frontend, CLI and core service calls be updated to make sure to include homeassistant: True if the core config dir is present in the backup?

It's backward compatible. The breaking change is more logical. But I will look into CLI to add an option for it, if that is not exists today
