buffet: Fix state update notification to GCD cloud server
Device state notification from buffet's state manager are coming
with state property names in form "package_name.property_name" and
that's how they were reported to the GCD server instead of being
split in JSON as {"package_name": {"property_name": value}}.
Also added "buffet_client GetState" command to retrieve actual
internal device state from buffet bypassing the GCD server-dependent
GetDeviceInfo. This is useful for debugging and also in case of
local-only workflow (with no GCD server present).
Finally, modified "buffet_client UpdateState" to allow complex
non-string state properties to be set. Now this command expects
a property name followed by a properly formed json value for the
property. Strings now require double-quotes. Integers, Booleans,
lists and dictionaries can now be set too.
