3709: arv-put now prints collection uuid by default.  Add --portable-data-hash
to arv-put to get the old behavior (print PDH).  Crunch-job uses arv-put
--portable-data-hash to get the PDH to put in the log field.  Crunch-job logs
both PDH and collection UUID.
Merge branch 'master' into 3709-arv-put-print-uuid
Merge branch '3709-arv-put-print-uuid' closes #3709
