Is your feature request related to a problem? Please describe.
In some of our installations we are using redis for multiple namespaces. In that case we need to distinguish between keys stored inside redis. If we use now RedisRouteDefinitionRepository keys could be overwritten by different namespaces.

Describe the solution you'd like
Add option to RedisRouteDefinitionRepository to provide custom value for currently static ROUTEDEFINITION_REDIS_KEY_PREFIX_QUERY.

Describe alternatives you've considered
Providing custom RedisRouteDefinitionRepository but don't know if autoconfiguration allows it at the moment.
