This enables install_puppet.sh to run successfully on
trusty with PUPPET_VERSION=3 set.
Add a util directory and a puppetmaster bootstrap
shell script.
Puppetdb-terminus versions are the same in trusty and
precise but are different than the puppet version number.
Also puppetdb-terminus isn't present in the puppetlabs
repositories.
Along with this I have done sufficient testing to use
puppet version 3.6 with confidence.
Work has been done to enable directory environments as well.
