Added a rule function map_to_redis_hset_args to help preparing redis HSET (or HMSET) multi-fields values.

For example, if payload.value is a map of multiple data fields, this rule SELECT map_to_redis_hset_args(payload.value) as hset_fields FROM "t/#" can prepare hset_fields for redis action to render the command template like HMSET name1 ${hset_fields}.
