Previously ACL checking was done in PKIRealm by matching the URL.
This code has been replaced by ACLInterceptor which will intercept
RESTEasy method invocations. This allows more precise mapping of
REST methods to ACL entries in acl.ldif.

Ticket #287

With this patch, it will be possible to install a default instance
simply by adding the passwords in the pkideployment.cfg.  This file
can then be used without additional alteration to add subsystems to the
same instance, by re-running pkispawn against the config file.

The patch makes sure that cert nicknames, database and baseDN , admin users
and client db are unique per subsystem.  An option is added to reuse the
existing server cert generated by the first subsystem and copy the
required data to all subsystems.

this method.

Ticket #309

A REST account service has been added to allow client to login
to establish a session and to logout to destroy the session. This
way multiple operations can be executed using the same session
without having to re-authenticate.
