Import kibana .deb to apt repository
As part of the upgrade of logstash.wikimedia.org to elasticsearch 2.3
kibana will also be upgraded to version 4.5. Kibana was previously
deployed with trebuchet due to local hacks, but that is no longer
necessary. Package has been tested in beta cluster and looks to be in
working order.
