Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "xci: Configure ansible verbosity based on job type"
  - xci: Configure ansible verbosity based on job type

    Daily jobs will use pinned versions of bifrost and openstack-ansible in
    order to make sure we use known good versions for them since focus of
    the daily jobs is  OPNFV platform testing.

    Ansible log can easily become massive depending on the level it is set
    and it is not so relevant for daily jobs to have it like this due to
    less probability of dailies failing to provision/deploy.

    On the other hand, the jobs that verify/test bifrost and openstack-ansible
    will have max verbosity enabled to troubleshoot these components themselves.

    New set of jobs will be created running periodically against the HEAD
    of master for bifrost and openstack-ansible to catch working versions
    and help us promote them to use for daily platform jobs. Verbosity of these
    jobs will be enabled like how we are doing for bifrost-verify jobs.
