Update git submodules

* Update puppet-storyboard from branch 'master'
  - Merge "Use a utf8mb4 collation"
  - Use a utf8mb4 collation
    
    Change I25bd7b5d2a904dad3e13efaf2da94cce205bcc0b switched the
    characterset for new databases to utf8mb4, but the Puppet MySQL
    module independently defaults the collate parameter to
    utf_general_ci which is not compatible with utf8mb4. Set an explicit
    utf8mb4_general_ci collation instead so that the database can be
    created successfully.

  - Fix second ServerAdmin conditional
    
    There are two ServerAdmin entries in the https vhost erb template. One
    for port 80 and one for port 443. The previous change only fixed the
    issue for port 80. Fix this for port 443 too.
    
    Additionally fix the ssl chain file variable which has the same problem.

  - Fix undef in vhost templates
    
    On puppet 3 an explicit undef value is evaluated as the symbol :undef in
    ERB templates, while on puppet 4 the explicit undef is evaluated the
    same as the implicit undef which comes to the nil value in ERB. Check
    for both values to make both puppet versions happy.

  - Set "AllowEncodedSlashes on" in vhost templates
    
    This is required to properly support handling requests for project by
    name, where the name may contain encoded slashes. For example,
    
      GET /v1/projects/openstack-infra%2Fstoryboard
    
    causes Apache to give a 404 error without this patch.

  - 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.

  - Merge "Fix scope of vhost template variables"
  - Clean the webclient unpack dir safely.
    
    Don't rely on a puppet file resource to purge the unpack dir as this
    will trigger on every puppet run then copy the empty unpack dir to the
    deployment dir. Instead we call rm prior to tar during the unpack exec
    so that we only ever clean the dir if we are unpacking.

  - Unpack webclient into dist subdir
    
    The old webclient tarballs had content in a "dist" subdirectory, but
    newer ones do not. So as to avoid webroot contamination as well as
    to make sure we copy the correct new content into place, unpack the
    tarballs into an empty "dist" subdirectory of the download staging
    directory.

  - Fix Tarball Naming
    
    Storyboard.o.o's webclient has been lagging behind master due to
    a change in naming.
    
    This patch fixes the tarball name so that the webclient in prod will
    actually reflect whats in master.

  - Fix scope of vhost template variables
    
    Dynamic scoping for variables in ERB templates was removed in puppet
    4[1] which means that the variables defined in the manifests cannot be
    found when it is referenced in the httpd::vhost defined type and will be
    evaluated as nil when puppet runs. Use scope.lookupvar instead to be
    explicit about the variable's source.
