Added initial code for retrieving transport cert.

Resources now extend CMSResource.
Addressed following review comments:
* check for null pointers in SystemCertificateResource
* move logic from CertificatData constructor to CMSServlet builder method
* remove unused field uriInfo and replace hard-coded cache constant
* fixed some formatting issues
