Make devserver record and present a detailed log of client events.
The devserver now stores a complete list of timestamped attributes, as
they are extracted from client messages. A log is indexed by client IP
addresses. Each of the events in a client's log is a set of attributes
and values, including the type of the event, a status code, the reported
board and OS version, and a timestamp. A dedicated HTTP API allows to
read client logs in JSON encoding. Previous client tracking
functionality is preserved for backward compatibility.
TEST=Unittests; complete update cycle of a chromebook client over
a network connection.
