All items currently filled in by credentials.py should come from options configured by the UI in home assistant.

The credentials.py script can be updated to handle ingest of these options and reporting them back to the main script.

Currently we log in once, and then never try log in again.

This can cause API calls to fail once the token expires. We need to safely handle that and try login again if we fail.

After a certain number of failures, we can probably safely stop trying and assume the username/password has change.

Bonus points:
Add another entity that we publish to home assistant, to indicate whether our last communication with the was successful. Binary sensory of type connectivity, and maybe a second binary sensor that indicates whether or not credentials have expired outright and you need to update your username and password for the integration.

Entites are currently hard coded as expected strings, and we have a little helper utility to generate the json dump for discovery and state publishing in home assistant.

We wanna move these into a class, and use dumps to convert those entities to valid json.

This should also help improve later down the road when we introduce setters and modifying settings from home assistant
