Update git submodules

* Update puppet-asterisk 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.

  - Ensure asterisk refresh happens last
    
    The new resource ordering algorithm in puppet 4 may cause the asterisk
    service to be refreshed before the module directories are in place,
    which then causes the module reload exec to fail. This patch adds an
    explicit ordering to the customdir defined type to ensure that the
    module directory exists before the asterisk service is refreshed.

  - Add beaker tests
    
    Add tests to ensure the asterisk class can be applied correctly and the
    service can start.

  - Update Gemfile for Zuulv3
    
    The logic in the Gemfile was relying on Zuulv2 variables to find out
    whether the spec helper gem was already available on disk, and since
    Zuulv3 has changed things it was failing to find it and downloading the
    master version instead. This patch ensures the Gemfile looks for the gem
    in the right place when running in CI.
