Migrate various platforms to config flow instead of yaml

[pinkywafer]

More components are able to be set up on the front end using config flow. Some have to be set up in config flow.
Consider migrating from yaml to config flow where available

NB I'm still using yaml for many integrations, and i like it as I feel it makes the config files more 'complete' but as some things can't be set up in yaml, and config flow is clearly the intended route forwards, it may be worth migrating

IMHO: I've moved to the UI setups more. Credentials and secret files sometimes confuse the users so I feel as though the change won't have a negative effect on the shareability of it all.
