Make rueidis store to be more user-friendly and be more performant,

1. Make Get() and GetWithTTL() return go string instead of rueidis.RedisResult to be more user-friendly.
2. Make Set() only accept go string value, since Get() also returns go string.
3. Make GetWithTTL() retrive client-side TTL without additional network roundtrip.
4. Pipeline SADD and EXPIRE while setting key tags to reduce network roundtrips.
5. Not to cache SMEMBERS while doing Invalidate(), since it will also be invalidated soon.
