Adding support for the InitialDate attribute

This change updates the server and managed object set to support
the InitialDate attribute. The InitialDate is set when the Create,
CreateKeyPair, and Register operations are invoked and can be
listed and retrieved with the GetAttributeList and GetAttributes
operations respectively. The server unit tests have been updated
to reflect these changes.
