ALF-14306: Merged DEV to HEAD (4.2)

Add priorities to transformers
   - Addition of a separate Transformers subsystem (holds configuration to allow JMX to be used to reset it on the fly)
   - Moved supported, unsupported and explicit transformation configuration from spring into transformers.properties in the subsystem
   - Moved all transformer limits configuration from spring and into transformers.properties with the exception of some added for thumbnails
     and the rendering service - not done as this code is known to be changing.
   - Added priority, errorTimes and thresholdCount to enable selection of transformers by priority.
   - Removed the concept of 'Explicit' transformation and replaced with priority and unsupported.
   - Added logging to aid in the creation of global properties and removal of spring configuration.
   - Implementation of spring pluggable transformation selector that uses priority.
   - Merging current state of code changes to allow other work in this area to take place.
