Update Couchbase Integration #3395
Description
Short description
The Alpakka Couchbase integration has not been updated in quite a while and is stated to reach the EOL.
It would be nice if someone stepped up to update it instead :)
Details
I am a Couchbase employee and have been working on the update. I still need to add some more of new tests, but wanted to create this issue for submitting a draft PR for potential suggestions and recommendations by devs.
Thank you!
