buffet: Hook up XMPP to deliver push notifications to buffet

Now using XMPP not only for the device presence but for delivering
push notifications, specifically COMMAND_CREATED notification and
extracting the command instance from the notification message.
Add the commands received over XMPP to the command execution queue.

The remaining tasks for XMPP (making polling optional, provide
notification channel configuration options for buffet, update the
channel changes on GCD server, etc) are coming in follow-up CLs.

BUG=brillo:458
TEST=`FEATURES=test emerge-link buffet`
     Tested this on the device.
