ble_client isn't logging service and charateristic like the docs say it should

[hachi]

The problem

Documentation at https://esphome.io/components/ble_client.html#setting-up-devices says adding a client and connecting should cause it to enumerate and dump services and characteristics including UUID.

The example output shows this at level INFO

@jesserockz on discord notes the service dump has moved to VERBOSE log level, but characteristic dump is not able to happen during scan/connect

I noticed that if I guess and add a sensor it will walk the single service I am querying and give me characteristics.

I was trying to use this so I can create a component or config to talk to an HPA-250B air filter.
