HPCC-25341 Add option to regression suite to execute an arbitrary command/script before aborting

Add new parameter '--preAbort' with 'None' by default value

Handle when preAbort is not 'None', execute the command and store its stdout
and stderr in same place where the other regression logs are stored under the
'[WUID]-preAbort.log' name.

Tested manually.
