[keycloak-user] Custom Social Login, cache access_token, Enterprise Wechat

[kkzxak47]

I managed to get infinispan running in customized identity provider, but
apart from predefined caches, I am not able to add new cache:
the error reads:
```

    ]
}
```

How can I set up a new cache in infinispan? What is the proper steps to
create it?
