The installer script has been modified to validate DS info in both
interactive and silent installation.

Ticket #472

A new mechanism has been added to specify the authentication methods that
can be used to invoke the REST methods. The AuthMethodMapping annotation
maps each REST method to a list of allowed authentication methods. When a
client calls a REST method, the AuthMethodInterceptor will intercept the
call and verify that the client uses an allowed authentication method.

Most REST methods that require authentication have been configured to
require client certificate authentication. Authentication using username
and password will only be used to get the installation token from security
domain.

Ticket #477

security domain.

The pkispawn has been modified such that the configuration file
and subsystem type are optional. The pkidestroy has been modified
such that the instance name and subsystem type are optional.
If any of these options are not specified they will enter an
interactive mode.

Ticket #380

* TRAC Ticket #488 - Dogtag 10: Fix CLI 'cert-find' clientAuth issue

* 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.
