Update git submodules

* Update kolla-ansible from branch 'master'
  - Merge "Fix empty match while setting supported_policy_files"
  - Fix empty match while setting supported_policy_files
    
    When supported_policy_files gets set under python 3.7 [1], the regex '(.*)'
    matches twice, once for the policy file name and once more for the empty string
    that follows the policy file name. This is new behavior under python
    3.7. [2]
    
    This leads to the replacement string being written out twice resulting
    in something like this: "nova_policy.yamlnova_".
    
    This patch changes the regex to '(.+)' ensuring there is no match success
    against the empty string.
    
    [1]:
    - set_fact:
        supported_policy_files: "{{ supported_policy_format_list | map('regex_replace', '(.*)', '{{ project_name }}_\\1') | list }}"
