Change from radix/v4 to go-redis due to high lock overhead on EncodeDecode. Current best performance vs all previous versions

[filipecosta90]

EncodeDecode now acquires a lock on radix/v4 which can represent a large overhead in scenarios of high load.

To avoid having radix/v4 impact this benchmark tool we're moving to the go-redis client ( with the change of redis/go-redis#2570 )
