Implement pagination and fix resourceVersion in storage.GetList method

[fabriziosestito]

We want to implement pagination in the GetList method.

When the user sends opts.Predicate.Limit true we will need to generate a continue token and limit the number of items we return.
If the user sends a continue token, we will need to parse it and return to the next page until there is nothing more to return.

Use https://github.com/kubernetes/apiserver/blob/master/pkg/storage/etcd3/store.go as a reference implementation.

Moreover, we will need to implement the list resourceVersion
For instance, grafana uses snowflake IDs https://github.com/intergral/grafana/blob/2f390b310c1eec9d9cb7ee8459090d5dc19d3c02/pkg/apiserver/storage/file/file.go#L92
