mirror table generating code: Properly handle 'block_on_errors' and 'cluster' features

Browse Source 
The device-mapper mirror CTR table has been changing over time.  This has
now been corrected to handle the old and new methods for invoking the
'block_on_errors' and 'cluster' features.  (The code that does this was
accidentally committed in the previous check-in.  This check-in finishes
the job.)
