Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Enable ShellRunner

    1. fix the bug 'ShellRunner' object has no attribute 'archive_logs'
    2. remove the testarea_supported because it's not very necessary for the test
       cases themselves and can make it a little more simple to add a test case
       with new test area
