Update git submodules

* Update docs/submodules/so.git from branch 'master'
  to ae62cbb1785ea581be62496170ce5595bacd51da
  - Merge "Removed MsoUtils.log() calls from CatalogDbUtils"
  - Removed MsoUtils.log() calls from CatalogDbUtils

    Refactored calls to MsoUtils.log() to use logger object already present
    in the CatalogDbUtils class.

    In addition the CatalogDbUtils class has been accepting MsoUtils object
    as parameter to constructor - which is not necessary and not aligned
    with style in rest of the groovy code.
