deploychef: adaptation of deploychef to support openstackchef

The deploychef package has been adapted to implement the
run-time functionality required by decentralized openstackchef
class.

It does this by executing a script (deploychef) which instruct chef-solo
to recreate configuration files from all template files placed
at

/opt/deploychef/cookbooks/openstack/templates/default

by openstackchef class at build-time.

The deploychef init script run-level is lower than run-postinsts
script, which runs all openstack post-install scripts at first boot.
The deploychef script makes a call to run-chefsolo script,
which then creates openstack configuration files from all template
files mentioned above as directed by a recipe file.
This enables us to reconfigure an openstack image on first-boot,
thereby, updating the image with environment variables like IP address.

Like the template files above, there is a list of all default
variables used by the services in an openstack installation.
These variables, like the templates files above are created by
the openstackchef class and saved to a file under deploychef
directory at:

/opt/deploychef/cookbooks/openstack/attributes/default.rb

Whenever it's desired to reconfigure an openstack deployment
with an updated value of any of the variables in the attributes file
above, the script file run-deploychef should be executed to
reconfigure the stack as shown below.

cd /opt/deploychef
./run-deploychef
