Rename EvictCache to ForwardedCacheEvictionHandler

The class listening to cache evictions is called CacheEvictionHandler
and it uses the Forwarder to send cache evictions to the other node.
ForwardedCacheEvictionHandler for the name of the class that must handle
the forwarded cache eviction is more clear than EvictCache.
