Integrate gating unit tests to puppet modules

This commit adds unit tests that can serve as a minimal
gate that verifies the Puppet modules work on the following
versions of Puppet:
  - 2.6
  - 2.7
  - 3.0
  - 3.1

and builds jenkins jobs for the following modules:

  - cinder
  - nova
  - glance
  - horizon
  - openstack
  - swift

The unit tests are implemented as a job-group in jenkins job builder
with a single project called puppet-module-unit that is set as the
check and gate for the stackforge projects.
