Whether some connection parameters of jedis need to be handed over to the user for configuration

Whether some connection parameters of jedis need to be handed over to the user for configuration

The first version in the absence of a large amount of data stress testing is not clear whether some parameters need additional tuning and configuration, I think the first version for the time being to achieve the function, wait until the later unified pressure test to actively expose some problems and then optimize the iteration, for the time being, the default parameters of jedis is sufficient for users to use. What do you think about it?
