Disable Couchbase and move WebFlux and Infinispan out of beta

[mraible]

Disable Couchbase as a prompt so v7 does not prompt users. Can be re-enabled once Couchbase for Spring Boot 2.4 is fixed.

@jhipster/developers Are y'all OK with moving WebFlux, Neo4j, and Infinispan out of beta?

#13797 seems a blocker for Neo4j.

@mshima I added a bug bounty to the issue. I'm also seeing issues with Neo4j when running jhipster jdl reactive-ms and running e2e tests. They fail when talking to the blog app that uses Neo4j. If I change the gateway to use Cypress, the tests still fail. These tests passed with beta 1.

At least Webflux should be stable now, but I’m not totally sure of its current quality level.

Regarding the neo4j issue I will check with Michael and Gerrit. I remember something similar when we implement it and I think it's something how neo4j/neo4j spring integration handles relations. So maybe we need to prevent using dtos to always have the full object.

Webflux -> we have no choice, because our gateway is by default with Reactive. It's pretty well tested with the JDL daily builds, so I'm confident, we can remove "beta"
Infinispan -> very few feedbacks, so I think it works

Neo4J -> not sure it's ready yet, we still have some issues
Couchbase -> broken for a while

@pascalgrimaud I re-added Beta to Neo4j.
