Update git submodules

* Update puppet-cgit 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.

  - Merge "Update Gemfile for Zuulv3"
  - Merge "Filter out link-local ipv6 address in loadbalancer"
  - Filter out link-local ipv6 address in loadbalancer
    
    On puppet 3, which uses facter 2, the $::ipaddress6 fact explicitly
    filters out all link-local address[1]. On puppet 4, which uses facter 3,
    the $::ipaddress6 fact only removes the link-local address if can find a
    better one[2]. The beaker tests reveal that haproxy won't bind to the
    ipv6 local address and will fail to start, with errors like:
    
      Starting proxy balance_git_daemon: cannot bind socket [fe80::5054:ff:fec5:7095:9418]
    
    This matters in CI test cases where the test nodes don't have real ipv6
    addresses.
    
    This patch restores the puppet 3 behavior of ignoring the ipv6 address if
    it's a link-local address.

  - Merge "Use httpd::vhost $content parameter"
  - Merge "Add beaker check of vhost template"
  - Merge "Add order to cgit package"
  - 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.

  - Add order to cgit package
    
    The httpd module uses the file resource with the purge option to clear
    out the httpd conf directory. On puppet 4, the resource ordering
    algorithm changed such that the directory purge happens before the cgit
    RPM adds a config file there, which means on the next puppet run it
    purges it again and bounces the service again. This cause the
    idempotency test in beaker to fail.
    
    This patch adds an ordering parameter to ensure that the cgit package is
    installed before the httpd class runs so that it doesn't have to clear
    out the httpd config directory twice. Since puppet 4 more or less tries
    to order resources in the order they appear, also swap the package
    resourcs and httpd class just to make it clear what order things should
    be in.

  - Use httpd::vhost $content parameter
    
    Use the new $content parameter of httpd::vhost instead of $template.
    This way, the template gets rendered within the scope where it assumes
    its variables are, and doesn't need to use the scope object which
    doesn't work within a defined type. This will ensure the template keeps
    working on puppet 4.

  - Add beaker check of vhost template
    
    A subsequent patch will change how the the cgit apache vhost will be
    defined, so add tests now to ensure that the future change produces
    identical config files.

  - Reduce vhost priority on default site
    
    Multiple vhosts with ssl/tls requires clients support SNI. Unfortunately
    older python2 does not. There are workarounds but in an attempt to
    influence vhost ordering for non SNI clients reduce the default vhost
    priority on the default site vhost.
