Classify disk/tape errors for TAS

We should improve TAS/end of tape session message to lessen the impact of errors that are not caused by the tape infrastructure. See https://gitlab.cern.ch/cta/operations/-/issues/928 for details.

We already have something similar: in DiskWriteTask, TapeReadSingleThread, TapeReadTask, etc, the watchdog remembers the type of the error. For example:

currentErrorToCount = "Error_diskOpenForWrite";

currentErrorToCount = "Error_tapeUnload";

      if (!currentErrorToCount.empty()) {
        m_this.m_watchdog.addToErrorCount(currentErrorToCount);
      }

However, this is not added to the log messages.
