Update git submodules

* Update python-zaqarclient from branch 'master'
  - Replace openstack.org git:// URLs with https://
    
    This is a mechanically generated change to replace openstack.org
    git:// URLs with https:// equivalents.
    
    This is in aid of a planned future move of the git hosting
    infrastructure to a self-hosted instance of gitea (https://gitea.io),
    which does not support the git wire protocol at this stage.
    
    This update should result in no functional change.

  - Properly pass the CA to requests
    
    We store the CA in request.cert, but it's not compatible with a cert. To
    pass the CA to requests, we need to set the verify argument.

  - Merge "Import zaqarclient-dsvm-functional job"
  - Merge "Remove PyPI downloads"
  - Import zaqarclient-dsvm-functional job
    
    Import the job from openstack-zuul-jobs and rename it according to
    naming rules.
    
    Add some cleanups:
    * Sort list of templates alphabetically
    * Use lower-constraints template instead of jobs

  - Merge "add python 3.6 unit test job"
  - Merge "switch documentation job to new PTI"
  - Merge "import zuul job settings from project-config"
  - Merge "Comply with Python PTI"
  - Remove PyPI downloads
    
    According to official site,
    https://packaging.python.org/guides/analyzing-pypi-package-downloads/
    PyPI package download statistics is no longer maintained and thus
    should be removed.

  - add python 3.6 unit test job
    
    This is a mechanically generated patch to add a unit test job running
    under Python 3.6 as part of the python3-first goal.
    
    See the python3-first goal document for details:

  - switch documentation job to new PTI
    
    This is a mechanically generated patch to switch the documentation
    jobs to use the new PTI versions of the jobs as part of the
    python3-first goal.

  - import zuul job settings from project-config
    
    This is a mechanically generated patch to complete step 1 of moving
    the zuul job settings out of project-config and into each project
    repository.
    
    Because there will be a separate patch on each branch, the branch
    specifiers for branch-specific jobs have been removed.
    
    Because this patch is generated by a script, there may be some
    cosmetic changes to the layout of the YAML file(s) as the contents are
    normalized.

  - Merge "Replace os-client-config to openstacksdk"
  - Merge "Update reno for stable/rocky"
  - Replace os-client-config to openstacksdk
    
    Since now os-client-config has been superceded by openstacksdk[1].
    So need to replace the os-client-config in zaqarclient to
    slove the issue that 'No module named os_client_config'.

  - fix tox python3 overrides
    
    We want to default to running all tox environments under python 3, so
    set the basepython value in each environment.
    
    We do not want to specify a minor version number, because we do not
    want to have to update the file every time we upgrade python.
    
    We do not want to set the override once in testenv, because that
    breaks the more specific versions used in default environments like
    py35 and py36.

  - Comply with Python PTI
    
    as described in
    https://governance.openstack.org/tc/reference/pti/python.html
    projects should use 'stestr' as unit tests runner.
    
    This patch moves unit and coverage tests to use stestr as test runner
    instead of nose.
