Cluster-awareness

I am running hapi 20. Following the documentation, the following configuration works fine on a single-instance redis server.

```
const Hapi = require('hapi')
const CatboxRedis = require('@hapi/catbox-redis');

const server = new Hapi.Server({
cache : [
{
name: 'my_cache',
provider: {
constructor: CatboxRedis,
options: {
partition : 'test',
host: 127.0.0.1,
port: 6379,
db: 0,
}
}
}
]
});
```

Is this configuration also cluster-aware (does it get redirected)? Or do I need to change the configuration to interface with a cluster?

Start by reviewing the @hapi/catbox-redis provider options and the Redis adapter's cluster behavior. The issue names no files or tests; done would mean establishing whether the shown configuration supports Redis redirection or what cluster-specific configuration is required, then documenting that result.
