KeyBuilder and hashed keys

[aspnet-hello]

From @JunTaoLuo on Wednesday, September 21, 2016 11:56:48 AM

Currently keys are strings. We may want to consider creating an abstraction of KeyBuilder that only creates a string for IDistributedCache based stores and use an object as the key for IMemoryCache based stores. We may also want to consider adding support for hashing the keys to a constant length

Backlogging this one.

It's unlikely we'll implement this unless there's more demand for this issue. However, we might consider this during the design of Output Caching.
