Adds Hiera implementation within Packstack

Packstack configures Hiera as data backend. Packstack puppet templates are now
using hiera() and hiera_array() functions to fetch data from hiera backend.

Packstack generates a defaults.yaml file in the /var/tmp/packstack directory.

Firewall rules for each openstack components are inserted into the hiera
backend as hash and created by the create_resources function.

Allow --default-password with --gen-answer-file

Previously, it was not possible to specify a default password when
creating an answer file. This patch fixes that by allowing to run
"packstack --gen-answer-file=<file> --default-password=<password".
The answer file will have the specified default password included.
