I'm using 7.17 client and I'd like to build ILM from java.

This is what I've tried:

```auto
final RolloverConditions rollover = new RolloverConditions.Builder()
        .maxSize("4GB")
        .maxAge(t -> t.time("1D"))
        .build();
PutLifecycleRequest.of(it ->
        it.name("ILM")
                .policy(policy -> policy.phases(
                        phases -> phases.hot(hot ->
                                hot.actions(JsonData.of(rollover)))
                )));

```

However it fails because the rollover isn't properly serialised. What is the proper way to add one or more actions to ILM phases?
