Update git submodules

* Update docs/submodules/releng from branch 'master'
  - CPERF: Fix ODL_STREAM to not include 'stable/'

    CSIT variable needs to be the branch short name. Also, removes duplicate
    log upload and fixes the upload path to use short name (to avoid '/' in
    path for branch)
