      Description

      All the ehcache specific beans need to be removed for the KNL-1162 work to be of real value (otherwise the beans actually can cause problems when trying to swap out to another caching system)

      This also means transferring the cache settings from those beans into the "standard" config mechanism (as controlled by the CacheInitializer):
      memory.

      {cacheName}

      =timeToLiveSeconds=3600,timeToIdleSeconds=900,maxElementsInMemory=20000,eternal=false

      Things we CANNOT remove that are EhCache specific (aside from the Cache and MemoryService impls):
      kernel/kernel-util/src/main/java/org/sakaiproject/memory/util/CacheInitializer.java
      kernel/kernel-private/src/main/java/org/sakaiproject/springframework/orm/hibernate/SakaiCacheProvider.java
