* Update docs/submodules/so.git from branch 'master'
  to dbd5bb99cd6a6c8a7465acb31468a07f2523f188
  - Use APIH credentials in 'mso.db.auth'

    Updated to use methods: env.getRequiredProperty() and msoLogger.error().
    Added the msoKey and the CryptoUtils.decrypt() code, and used
    "mso.camundaAuth".
    Used APIH credentials in 'mso.db.auth' as source instead of
    'mso.camundaAuth' (need decrypt code by CryptoUtils).
