Previously the link to the initscript was named the same name as
the instance name: /var/lib/pki/<instance>/<instance>. It has now
been renamed to /var/lib/pki/<instance>/initscript to make it more
consistent.

Ticket #422

The default deployment configuration has been renamed and moved to
/etc/pki/default.cfg to make it more accessible to users. The pkispawn
has been modified to archieve the default deployment configuration
along with the user-provided configuration in the registry. The
pkidestroy will now use both archived configuration files to ensure
proper removal.

Ticket #399

This patch replaces the code in pkiparser with defaults that are
built up using ConfigParser interpolation.  The patch gets most
(but not all) default parameters.

The messages in ProfileList.template in CA EE has been extracted
into a properties file which can be translated separately.

The original messages in the template have been marked as follows:
  <span class="message" name="...key...">...message...</span>

When the page is loaded into the browser, the original message will
be replaced with the translated messages.

Ticket #406

We need to keep the admin cert and p12 file in case the client directory
is purged.

Previously the deployment tools used symbolic links to determine the
scriplets to execute and their order. The code has been changed such
that now the scriplets are listed as parameters (spawn_scriplets and
destroy_scriplets) in the configuration file.

Ticket #403

Previously to create a subsystem the admin would have to copy the
entire default deployment configuration, which contains many
parameters, and then customize it. Now the deployment code has been
changed such that the default config file will be used to provide
the default values, so the admin will only need to provide the
non-default parameters, thus reducing the size of the file.

Sample configuration files are provided in /usr/share/pki/
deployment/config.
