Split dnsmasq-packages, fixing related issue

As a result of this error, 

```
ebug: Executing '/etc/puppet/etckeeper-commit-pre'
debug: catalog supports formats: b64_zlib_yaml dot pson raw yaml; using pson
err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find resource 'Package[dnsmasq-base]Package[dnsmasq-utils]' for relationship on 'Package[neutron-dhcp-agent]' on node controller6.ec2.internal
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
```

I split the $dnsmasq-package in two and resolved the issue I was facing.
