Mirror puppet5 for Ubuntu Bionic

Puppet 5 has now been released officialy [1] for
Ubuntu Bionic so we don't have to use the nightly
builds anymore [2].

This adds bionic to be synced from apt.puppetlabs.com
but also changes the structure of the template and the
releases variable to support the Components param for reprepro.
