    Add exception clause and logs for subcloud audit

    Added an except clause to log uncaught exceptions that may happen when
    _subcloud_audit function is called.

    Test Plan:
    PASS: In a DX DC system with AIO-SX subcloud offline, observe the log
          exception message and callstack traceback to be thrown on the
          /var/log/cert-mon.log file, as code execution proceeds to
          finally clause in do_subcloud_audit function.
    PASS: In a DX DC system with simplex subcloud online, force an invalid
          subcloud audit item to assume None value. Observe the log
          exception message and callstack traceback to be thrown in the
          /var/log/cert-mon.log file, as code execution proceeds to finally
          clause in do_subcloud_audit function.
