RESTful servlet to configure system in a single servlet.

Installation code common to the panels and the installation servlet are extracted to a
ConfigurationUtils file.  The panel code will be cleaned up to use the code in this
class in a later commit.

Contains restful client and test driver code.  The test driver code should be modified
and placed in a junit/system test framework.  Installation has been tested to work with
the following installations: master CA, clone CA, KRA, OCSP, TKS, subordinate CA, CA
signed by external CA (parts 1 and 2).
