Add support of lua function 'redis.setresp()'

[git-hulk]

Except for the redis.setresp function, it fixes the different behavior with Redis in Lua script.

Before applying this PR, the Lua script will return the result in RESP3 format
if the connection is connected with HELLO 3 command. But for Redis,
it will always use RESP2 unless users explicitly set it with redis.setresp(3).

// Kvrocks

❯ redis-cli -3 -p 6666

127.0.0.1:6666> EVAL 'return redis.call("hgetall","hash")' 0
1# "f1" => "v1"

// Redis

❯ redis-cli -3 
127.0.0.1:6379> EVAL 'return redis.call("hgetall","hash")' 0
1) "f1"
2) "v1"

After applying this PR, it will behaves consistently with Redis:

❯ redis-cli -3 -p 6666
127.0.0.1:6666> EVAL 'redis.setresp(3);return redis.call("hgetall","hash")' 0
1# "f1" => "v1"
127.0.0.1:6666> EVAL 'return redis.call("hgetall","hash")' 0
1) "f1"
2) "v1"
