…eAsCollection, changes the default repository cache to be an isolated cache (instead of part of the single main dictionary cache), adds the logic for the cache option GetAllCacheAsCollection to RepositoryBase, updates Language and Domain repositories to use GetAllCacheAsCollection, updates RepositoryFactory to be the one responsible for injecting a DeepCloneRuntimeCacheProvider and to use a single _noCache instance.

…loneableList + tests. Updates RepositoryBase to use DeepCloneableList when GetAllCacheAsCollection is used (so that all entries that get cached are deep cloned into and out-of the cache). Adds test for DeepCloneRuntimeCacheProvider for dealing with this list type.

…ere required, refactors how IsolatedRuntimeCache is exposed on the CacheHelper, ensures that IsolatedRuntimeCache is used in all repositories instead of the global RuntimeCache, changes all obsolete usages of CacheHelper to the non obsolete equivalent, obsoletes many of the cache keys, obsoletes a couple cache refreshers that aren't used anymore in 7.3, simplifies CacheHelper with regards to it's 'disabled' cache state.

… - to basically disable it since there could be tons of these and currently an IDictionaryItem is a massive entity (need to fix that)

…single key even if there were ids specified which is wrong. Updates TemplateRepository to use a single GetAll query as its base source and it uses the GetAllCacheAsCollection option, also massively simplifies its GetDescendants methods, obsoletes some unused code,

…and return a single result by ID based on the cache of GetAll

…c access item is deleted.

…ed ILanguage entity is not cached nor cloned. This will save on lots of memory and cloning cycles especially if there are quire a few dictioanry items. Unfortunatley to achieve this requires a not so pretty hack where we need to assign an internal callback to the model so it knows how to retrieve the language when it needs it. In v8, the ILanguage entity will not be attached at all. This also fixes a cache refresher issue for when a language is deleted -> all dictionary cache must be removed. This commit also changes a method name: ClearAllIsolatedCacheByRepositoryEntityType
