  1. New column MON$PARALLEL_WORKERS INTEGER were added into MON$ATTACHMENTS table.
  2. New variable PARALLEL_WORKERS is available in SYSTEM context.
  3. New tag fb_info_parallel_workers (value 149) is available in IAttachment::getInfo() and isc_database_info() calls.

@@@ QA issue @@@

Currently test checks only ability to query values from mon$attachments and rdb$get_context.
It does NOT check tag fb_info_parallel_workers because this is not yet implemented
(BTW, 'isc_dpb_parallel_workers' also not yet avaliable in the firebird-driver).
