deploychef: makes chef-solo templates from openstack conf files

The current openstack build bakes a number of variables into openstack
services' configuration files at build-time. This makes it impossible
to deploy an openstack image built for one run-time environment into a
different run-time environment.
The deploychef package uses chef-solo to enable the re-use of an
openstack image in different run-time environments.

The attached patch set is deploychef package recipe and init script
files. The script deploychef.init gives us the ability to make a copy of
the postinstall script before they are tainted. This enables us to create
chef-solo templates out of the untainted postinstall scripts.
The template files are then used to recreate the postinstall script
whenever the stack needs to be reconfigured at run-time.
