Update git submodules

* Update docs/submodules/qtip from branch 'master'
  - Merge "metrics baseline in compute-baseline.json"
  - metrics baseline in compute-baseline.json

    - Previously, metrics baseline are defined in the spec file.
    In this patch, move metrics baseline to compute-baseline.json.
    - you can get qpi based with baseline file given in calculate.yml
    - you can generate a customized baseline file when baseline file is
    not given in calculate.yml

    And baseline will be removed from the spec file.
