Metacat

Implement CNRead.synchronizationFailed() in MNodeService. Note: The CN URL is not yet available in the SynchronizationFailed exception, but will be once the d1_common_java exception is updated. See https://redmine.dataone.org/issues/1656. Once updated, change this method to explicitly state the CN URL making the call.

Change Metacathandler.read() to be public since it's internal to Metacat, and use read() in D1NodeService after isAuthorized() for the calling Subject from the Session object.

Implement MNRead.listObjects() in MNodeService.

Implement MNRead.describe() in MNodeService.

Implement MNRead.getChecksum() in MNodeService.

Minor formatting changes - tabs to spaces, indents, etc.

Implement [MN|CN]Read.get() in D1NodeService. Added setParamsFromRequest() to pass through parameters from the request object. Since the D1 Authorization API doesn't specify which authentication system a subject belongs to, we don't know if the subject listed is a KNB LDAP DN. isAuthorized() may return true for a mapped identity, but we don't know the DN of the KNB identity per se. This needs to be tested.

-use every Subject in the session (alt Ids and Group membership)
-consolidate to single isAuthorized method

throw exception for unimplemented methods
