[FEATURE] 📢 Expose the current backplane, if any #445
Description
Problem
Currently, given a FusionCache instance, it's only possible to know if there is a backplane via the bool HasBackplane { get; } property, not which one it is.
Recently community user @angularsen asked to expose it in #443 .
Historically I've been hesitant to expose internals, but at this point I think I can let this one go.
Solution
Add a new IFusionCacheBackplane? Backplane { get; } property that expose the IFusionCacheBackplane instance being used, if any.
Alternatives
Some fragile reflection magic stuff, so, yeah.
