Description

The current implementation of the RedisIdempotentRepository uses a (Redis) set as the underlying data structure. This is conceptually nice for keeping all consumed keys in a single logical location. However, it makes the management of keys more difficult, since we cannot use Redis' built in mechanisms for expiring keys and have to do a manual cleanup.

Thus, this issue proposes to use Redis String as the datatype for a single entry in order to provide support for expiring keys. If the community is in favor of this idea, I am happy to provide a patch (or a second, alternative implementation).
