Is BluetoothAdapter the right name here? I thought we were moving to calling
things "Interface"?

nit: Add a comment about the class.

See WebBluetoothServiceImpl for example:

Since everything is a WIP, this file will change many, many times so it's
probably OK for now. however, I haven't heard anything about using "Interface"
in the service implementation. Was this in the design doc discussion?

This is not really a big issue but I was just wondering what the right name for
this should be. I think there are a couple of issues here:

1. From the examples I've seen if the interface's name in the mojom is "Adapter"
the class that implements the interface should be called "AdapterImpl".

2. Is the name "Adapter" correct? Should it include the name "Interface" or
"Service" in there?
