  - Merge "Hid MsoUtils.log() methods from public use"
  - Hid MsoUtils.log() methods from public use

    The MsoUtils class has utility methods for logging made publicly
    available (by default groovy scope). With changes to logging subsystem,
    other classes should not use them for logging - so they have been made
    private.

    This is last commit in a series to eliminate use of MsoUtils.log() from
    other classes and should prevent such usage in future.
