With changes made to the identity class, the postinstall
scripts no longer register users and services with keystone.
Instead, the registration is put inside the file
/etc/keystone/service-user-setup by the postinstall scripts.
Executing /etc/keystone/service-user-setup then registers
the users and services with keystone through /etc/keystone/identity.sh.
Therefore, executing just the postinstall scripts is not enough
enough to properly bring up the stack. However, executing
/etc/init.d/run-postinsts does both.
In addition, we are executing scripts within run-deploy in the
current shell environment so that the user can see all the updates
to the databases on the terminal.

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

Deploychef package reconfigures an openstack installation.
These are helper files used by the deploychef package to bring the
system down and back up again before, and after chef-solo has generated
our desired configuration files from template files.
Later on in this commit series, the *-list files will be replaced with
dynamically generated *-list files by openstackchef. In addition,
the script files will be adapted to support openstackchef.
