Add Sync from Cloud for new athlete

.. when a new athlete is created and opened the blankstate page
   currently provides options to get data by importing files or
   downloading from a device.

.. this update adds the ability to configure a cloud service and
   start a sync straight away

.. this UX is introduced since cloud services are now much
   more ubiquitous and v3.5 introduced broad support for a wide
   range of services.
