Add directory into releases archives (#243)
Add directory into releases archives (#243)

In order to align release tarbals with other community prom exporter releases it may be good to have the folder inside tar.gz archive like for example here:
https://github.com/prometheus/node_exporter/releases/download/v1.0.1/node_exporter-1.0.1.linux-amd64.tar.gz
We need this to deploy all exporters with single Ansible role https://github.com/entercloudsuite/ansible-prometheus-exporter
Current archive dirrectory structure breaks this flow.
