Update git submodules

* Update puppet-zanata from branch 'master'
  - Preparation for Zanata 4 version upgrade
    
    There are some different changes in standalone.xml between
    Zanata version 3 and 4. A version flag is implemented to
    rollout the right version from template dir. For backwards
    compatibility Zanata version 3 and 4 are supported yet.
    Wildfly 9 stuff is removed because we have still Wildfly 10
    running. That simplifies the manifest. Switch download URLs
    to github, so there is also a standard to fetch files.
