Is your feature request related to a problem? Please describe.

Right now native cosmo subscriptions are now possible only via NATS/Kafka. Not every team has those in their stack, I believe that Redis is much more commonly used, would be great to see it as an option

Describe the solution you'd like

Apollo has a package on NPM to support subscriptions over several subgraphs. https://www.npmjs.com/package/graphql-subscriptions. As a nodejs developer I see that redis is most used package https://www.npmjs.com/package/graphql-redis-subscriptions, more over this package works not only with apollo server, but with other graphql servers for nodejs as well, I am using yoga for example. Would be ideal if cosmo router would be compatible with graphql-subscriptions from Apollo, so cosmo routed subscribed to Redis and nodejs developers can use this package as a client to send messages to Redis
