Vagrant updates for Fedora 22

Vagrant updates for Fedora 22

Make more updates so that Fedora 22 is able to be managed in both the
baseline as well as lf_network Vagrant definitions

* This swaps out the lex-dnsmasq puppet module for saz-dnsmasq
* This cleans up the puppet manifest to be puppet-lint safe
* This cleans up the puppet manifest to be puppet 4 compatible as F22
  has puppet 4 in the upstream
* We throw away the "cloud-init-post" scripting that was originally
  being done on EL & Fedora systems as we have been using better
  techniques that do not require it
