Update git submodules

* Update docs/submodules/releng/builder from branch 'master'
  to 2d78e202f34be4b5d792e35727d20c28aac290ae
  - Merge "Use log4j2 size config instead of maxFileSize"
  - Use log4j2 size config instead of maxFileSize

    karaf 4 uses log4j2 rather than log4j. The newer api uses
    different config for the maxFileSize.

    Use the new common-functions to set the karaf logging.
