* Update docs/submodules/bottlenecks from branch 'stable/fraser'
  - Merge "bug-fix: fix key error in soak throughputs CI" into stable/fraser
  - bug-fix: fix key error in soak throughputs CI

    In the redundant information deleting patch, results of each
    thread running is removed from message Queue resulting in
    counting the overall success threads in error status
