We update the default logstash dashboard to remove excessively short
refresh period options, default the query result listing output to
be timestamp and message, default to a 15 minute query instead
of a 24 hour query, and default to a blank query instead of '*" because
the '*' forces you to delete it to add any new queries but they are
functionally equivalent.
