Add support for MemoryDB/ElasticCache/Redis as Idempotency backend

[whardier]

Updated topic to mention ElasticCache and general Redis as well.

I'm putting myself available to tackle this issue.

That would be awesome! I think vanilla Redis makes more sense than MemoryDB as it’s still early to know how many customers would want it. FYI - I’m back on Sep 27th and will review the PR by then. Muito obrigado Guilherme ;-)

Isn't it meant to be the same client implementation for both?

[heitorlessa]

Yep, though I haven’t had a chance to look into it yet for any caveats.

Just read the docs, you’re right Daniel, it’s fully compatible — we could use redis-py-cluster as an optional dependency. Depending on the implementation, it’d be easy to also provide Redis support for Parameters and Feature Flag. https://github.com/Grokzen/redis-py-cluster

Redis in general would be fairly rad to have available via an extra requirement. I wasn't entirely sure if a broad implementation in aws-lambda-powertools for redis support would ultimately support both ElasticCache and MemoryDB.

@heitorlessa . Things have changed, won't have bandwidth to tackle this issue :/. I hope someone else will volunteer. Enjoy your time ! Obrigado 👍
