Add gate job configuration for Chef cookbooks

This commit adds the Jenkins job builders and gate
configuration for the Chef cookbooks. Only the
cookbook-openstack-common repo is changed from a
NOOP gate to the lint + unit gate at this time, as
that cookbook is the first that will be going into
the Stackforge repo.
