* Update docs/submodules/dovetail from branch 'master'
  - [cvp-web] Admin can approve and not approve results

    JIRA: DOVETAIL-562

    According to the CVP workflow, once a result has been submitted to review,
    the admin will send email to all reviewers to get the comment (+1 / -1).
    Enable admin to approve/not approve the result after he gets the feedback from all reviewers.
    Otherwise, the result will always be in 'review' status.
