Previously the context.xml files are deployed into META-INF folders
in each webapps. They now have been moved into <instance>/conf/
Catalina/localhost/<subsystem>.xml to allow further clean-up.

Previously nonces were stored in a global map which might not scale
well due to some issues:
1. The map uses the nonces as map keys. There were possible nonce
   collisions which required special handling.
2. The collision handling code was not thread safe. There were
   possible race conditions during concurrent modifications.
3. The map was shared and size limited. If there were a lot of
   users using the system, valid nonces could get pruned.
4. The map maps the nonces to client certificates. This limits
   the possible authentication methods that can be supported.

Now the code has been modified such that each user has a private map
in the user's session to store the nonces. Additional locking has been
implemented to protect against concurrent modifications. The map now
uses the target of the operation as the map key, eliminating possible
collisions and allowing the use of other authentication methods. Since
this is a private map, it's not affected by the number of users using
the system.

Ticket #474

* Added RESTful servlet to add/remove a KRA connector from the CA.
* Modified ACL to allow KRA subsystem user to remove connector.
* Modified connector code to allow the connector to be replaced without a server restart.
* Added functionality to pki CLI to add/remove connector
* Added code to pkidestroy to remove the connector (using both pki CLI and sslget)
  When the issues with pki connection are resolved, we will use that method instead.
* Modified sslget to accept HTTP return codes != 200.  In this case, we were returning
  204 - which is perfectly legitimate.

Ticket #418

The paths to RESTEasy jar files have been modified such that it can
be configured globally at build time using the spec file to support
different distributions, and at deployment time using a system-wide
configuration in /etc/pki/pki.conf.

Ticket #422, #423.

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

1. Modified cmake dependency
2. Corrected conditionals in spec file
3. Added paths for resteasy-base
4. Added paths to policy for resteasy-base
