add crc32hash and compatible with RedisShardAPI

[SeaSand1024]

When we use RedisShardAPI in python with crc32hash, we can't compatible with Jedis,In addition, we will also add sharding algorithms,because it is different from python.

@SeaSand1024 Have you checked if this implementation is actually compatible with RedisShardAPI?

Yes, I did. You'd better specify the format of HostAndPort the same as python if you use ShardedConnectionProvider.The default format is "host:port".

[sazzad16]

Sharding feature will be removed.
