Description

We added backward compatibility for two config parameters in CASSANDRA-17141 to fix a bug but I realized that with the current setup, a warning for deprecated parameter can be logged more than once which is not needed and only introduces noise to the logs. 

I already fixed that in CASSANDRA-15234 where this would lead to a lot of warnings and it is easy to spot. I will backport the tiny fix here too in case we add more parameters, etc; to prevent the potential noise.
