HASSIO: Adjust hassio config.json to map all data relevant directories

[Frintrop]

Describe the bug

In HASSIOs config.json only "config" is a mapped volume to hassio host.
Which mappings have to be configured for sqlite database and other configurations like SOC limit for chargers, soc handling for battery ?!

Steps to reproduce

Update HASSIO version of evcc..
Sometimes many configs are gone...

Configuration details

network:
  # schema is the HTTP schema
  # setting to `https` does not enable https, it only changes the way URLs are generated
  schema: http
  # host is the hostname or IP address
  # if the host name contains a `.local` suffix, the name will be announced on MDNS
  # docker: MDNS announcements don't work. host must be set to the docker host's name.
  host: xxx
  # port is the listening port for UI and api
  # evcc will listen on all available interfaces
  port: 7070

interval: 30s # control cycle interval. Interval <30s can lead to unexpected behavior, see https://docs.evcc.io/docs/reference/configuration/interval

#database configuration for persisting charge sessions and settings
#database:
#   type: sqlite
#   dsn: /config/evcc.db

Did you change any Add-On configuration defaults? The default paths are

config_file: /config/evcc.yaml
sqlite_file: /data/evcc.db

and that's quite fine. /data is a persistent volume which is only accessible to that specific addon. More documentation can be found here https://developers.home-assistant.io/docs/add-ons/configuration/

Actual there is only /config as volume configured and not planned to move to addon_config.

@Frintrop @goebelmeier I also just had a look at this, because I was thinking about the same problem. I just restarted the evcc container and checked the creation time of the evcc.db. It looks fine. For example:

Sep 25, today we have the 27 so the file is not being re-created. I think this can be closed

@Frintrop Note that the map config documentation says:
Note that the data directory is always mapped and writable, but the path property can be set using the same conventions.
