* Refactoring data_entry_flow and config_entry_flow
Move SOURCE_* to config_entries
Change data_entry_flow.FlowManager.async_init() source param default
to None
Change this first step_id as source or init if source is None
_BaseFlowManagerView pass in SOURCE_USER as default source
* First step of data entry flow decided by _async_create_flow() now
* Lint
* Change helpers.config_entry_flow.DiscoveryFlowHandler default step
* Change FlowManager.async_init source param to context dict param
* Always return bytes from auth.providers.homeassistant.hash_password
Good for interface cleanliness, typing etc.
* Add some homeassistant auth provider type annotations
