Add phoenix_part* jobs in non-voting mode

Add phoenix_part1 and phoenix_part2 jobs in non-voting mode to the
following pipelines:

  trafodion/core : check, check-full, gate
  trafodion/dcs : check, check-full, gate
  trafodon/phoenix_test : check, gate

Once these two jobs are considered stable they will become voting
and replace the existing phoenix_quick or phoenix_test job that is
currently being run.
