Add random cache and replace SharedLRU in KeyValueStore

SharedLRU plays pool performance in KeyValueStore with large header cache size,
so a performance optimized RandomCache could improve it.

RandomCache will record the lookup frequency of key. When evictint element,
it will randomly compare several elements's frequency and evict the least
one.
