added method getLocalZone() to EVCacheClientPool
Added proxy methods on EVCacheClient to support (spy)MemcachedClient methods getUnavailableServers(), getAvailableServers(), flush(), getStats(), shutdown().
added destroy() method on EVCacheClientPoolManager, which shutdowns an App's EVCache pool and remove it from the list of managed pools
added EVCache support to auxiliar methods that will aid in testing and administration (flushAll(), shutdown(), getTranscoder(), getLocalAvailableServers(), getLocalUnavailableServers(), getLocalStats())
