Migrate HomeAssistant Config Files Location

[krkeegan]

Proposed change

The new location will be backed up by a Home Assistant snapshot and is Home Assistant's preferred location for storing config files going forward.

1. If a config.yaml file is not found in the new location; AND
2. A config.yaml file is found at the old location; THEN
3. Copy the entire contents of the old config directory to the new one
4. Add a notice file to the old config directory telling users:

• The new location of their config files
• That they can delete these config files if everything is working correctly.

This process should ensure that no data is lost and should provide enough guidance to users on where their config files are located.
