Core: OZW is causing error on startup - Missing async_step_hassio

[RogerSelwyn]

The problem

Since 111 the error has appeared in my logs at startup. As far as I can see it is triggered by OZW.

Environment

• Home Assistant Core release with the issue: 0.111.3
• Last working Home Assistant Core release (if known): 0.110.7
• Operating environment (Home Assistant/Supervised/Docker/venv): Hassio/Ubuntu/Parallels/Mac
• Integration causing this issue: OZW
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/ozw

Additional information

I tried adding async_step_hassio to relevant config_flow.py, which then changed the error indicating that core was trying to call that method, but not sure what should be the content of that step to remove the original error.

Adding a small note to this for the OZW team:

This is automatically fixed with core 0.112, as there is default handling for this now.

Hey there @cgarwood, @marcelveldt, @MartinHjelmare, mind taking a look at this issue as its been labeled with a integration (ozw) you are listed as a codeowner for? Thanks!

Thanks frenck if it is fixed in 0.112, this can be closed if there is no need to fix from the OZWNode team.

Thanks for reporting!
