Change log level when retrying connection with redis on JedisCacheListener

[wallysoncarvalho]

Issue

I believe that an attempt at retrying a connection should not be considered as an error, instead we maybe should consider error if the retry attempt fails. What do you think we change the level of the log to WARN and log error only if the retry is interrupted?

Use case

On my team we consider log level ERROR a situation where we should act to fix, this is not one of these situations because the service "heals itself".
