[PATCH BlueZ 1/2] shared/gatt-client: Add bt_gatt_client_clone

[Luiz Augusto von Dentz <luiz.dentz@xxxxxxxxx>]

From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This adds bt_gatt_client_clone which can clone existing client skipping
the discovery phase and creating separate queues so that all requests
done using the clone can be cancelled separately.
