* Update docs/submodules/dovetail from branch 'master'
  - [cvp-web] Allow accounts with role 'reviewer' to submit resuts

    JIRA: DOVETAIL-549

    Accounts within the CVP portal with the role 'reviewer'
    cannot submit test results currently.
    While reviewers cannot review their own results,
    they should be able to submit results.
    Many within the Dovetail community will be serving
    multiple roles as testers and reviewers.
