Add initial test env setup (#24)

This will deploy via the CI, as long as the environment variables are set in gitlab:

• SSH_PRIVATE_KEY (the private key for the leap_ci@remotevirt.riseup.net remote libvirt machine)
• GEOIP_ACCOUNT_ID (the geoip account ID)
• GEOIP_LICENSE_KEY (the license key that is associated with the above account id)

(I've added these CI variables to this project already)
