[FEATURE] 🐵 Add `ChaosPlugin`

[jodydonetti]

Problem

FusionCache already has a set of chaos-engineering related classes, like ChaosBackplane and ChaosDistributedCache, to ease testing how the system reacts to malfunctioning components, but in a controlled way.

Currently though, a ChaosPlugin is missing, and this should be fixed.

Solution

Add a ChaosPlugin, which will be an implementation of IFusionCachePlugin, and put it in the related project/package, ZiggyCreatures.FusionCache.Chaos.
