Support configuration options for cache entries (DistributedCache)

[pergerch]

Implement the options similar to #6 for DistributedCache.

DistributedCacheEntryOptions does not support a Priority, so we could display a warning and skip the priority property.

Remaining 2 properties to consider:

• int AbsoluteExpirationRelativeToNow (in seconds)
• int SlidingExpiration (in seconds)
