Do not deserialize StringRedisConn pipeline/tx results by default

- Change StringRedisConn to not deserialize pipelined/
exec results by default

- Remove option to enable/disable deserialize of
results in StringRedisTemplate. In most cases, the
same StringRedisConn is not used b/w ops in a pipeline 
or tx, so this is rarely useful
