[fronius] Config updates are not handled properly by Thing handlers

[florian-h05]

Expected Behavior

When updating the bridge config, e.g. username and password for the admin UI,
both bridge and inverter Thing should get the updated configuration.

Current Behavior

One needs to re-enable both bridge and inverter Thing.

Possible Solution

Implement config update handling.

Steps to Reproduce (for Bugs)

1. Update the bridge config, e.g. for battery control crendentials.
2. The inverter Thing will not use the new config.
