Merged from branch DEV/mward/head_cachefactory_conf to HEAD

54858: ALF-19668: Further cache configuration overrides
  54859: ALF-19668: added clustered cache types to properties, e.g. createLocalCache, createCache, createInvalidateRemovalCache.
  54867: ALF-19668: ClusterAwareCacheFactory now uses *.cluster.type properties to determine cache type.
