Changes:

• Rework of the event handling in CacheManager. Events are now more reliable and are now also getting triggered in multi instance scenarios using the backplane feature. Also, introduced an Origin property on the EventArgs which indicates where the event got triggered
• GetOrAdd and Update/TryUpdate were throwing exceptions a little inconsistently. Introduced a new TryGetOrAdd method

Bugfixes:

• Setting expiration mode to None for an individual cache item not working in some cases
• Serializer settings are not getting applied correctly
• Redis configuration via config file doesn't respect database if connection string is used
