Observed on master / 8.0.0.

When using the setup.dashboards.file option, setting it to a zip file containing Kibana dashboard files, Packetbeat does not actually load the dashboards in the zip file into Kibana.

Relevant settings in packetbeat.yml:

setup.dashboards.file: /path/to/dashboards.zip
setup.kibana.host: "localhost:5601"

Note that if the zip file is extracted and the setup.dashboards.directory option, pointed to that folder, is used instead of the setup.dashboards.file option, the dashboards do get loaded into Kibana as expected.
