Description

As redis does not support caching null values, currently in the implementation of redis-cache a check is there to throw a exception if the value is null. However, there can be a configuration to safely ignore the null value instead of throwing exception or trying to store it.

Same was discussed in #39547, hence creating this issue to have a configuration parameter which can achieve this behavior of safely ignoring null values instead of trying to save it in cache or throwing exception.

Implementation ideas

A parameter like cacheInfo.ignoreNullValues before the block where the exception is thrown
