Feature Request: Ability to be able to disconnect already connected devices

For example when something goes wrong and you don't get to disconnect nicely from a device, the next time you try to discover that device it is no longer available so you cannot connect to it again.

The ability to get a list of currently connected devices, then check if they offer the service you care about then disconnect them would be great. Similar to in the Adafruit BlueFruitLE libraries disconnect_devices([SERVICE_UUID]).

Otherwise, a great library, works well...
