Code Issues Proposed changes

Update git submodules 

* Update kolla-ansible from branch 'master'
  - Merge "Performance: use import_tasks for register and bootstrap"
  - Performance: use import_tasks for register and bootstrap
    
    Including tasks has a performance penalty when compared with importing
    tasks. If the include has a condition associated with it, then the
    overhead of the include may be lower than the overhead of skipping all
    imported tasks. In the case of the register.yml and bootstrap.yml
    includes, all of the tasks in the included file use run_once: True.
    The run_once flag improves performance at scale drastically, so
    importing these tasks unconditionally will have a lower overhead than a
    conditional include task.  It therefore makes sense to switch to use
    import_tasks there.
    
    See [1] for benchmarks of run_once.
