Cloud storage: modify protocol for checking cloud connectivity

In order to allow the backend to match account in multi user mode, it
needs to know if the requests are coming from the same instance of
Subsurface. Since I had to change the backend to add the ability to
retrieve a location service userid I added this capability at the same
time.
