📄 Description

For me the old method with QBluetoothDeviceDiscoveryAgent the connecting was pretty unstable.
It was disconnecting after a short amount of time, always. Since we already rely on BlueZ (only supported backend in Qt for Linux), I use the bluez dbus api to check for connected/disconnected devices.

Our Qt code than only connects to the service, not the device itself.

With this change I noticed a improvement in the time it takes for the app to connect to the airpods.

It's a pretty big change, and I wanna know what you think about it (@kavishdevar). I only noticed improvements.

Upsides I know of:

Improved connection speed
Improved connection reliability
Reduced resource usage (for my debug build, CPU usage not even measurable, RAM 102.4 MiB)

Possible downsides:

App doesn't auto-connect to airpods (since the system decides it). We could implement it
