Hi,

RegisterNamespace throws an error saying “Invalid RetentionDays” when my retention in days is \> 30  
I am using below code to register namespace

```auto
WorkflowServiceStubs service = WorkflowServiceStubs.newInstance(WorkflowServiceStubsOptions.newBuilder()
                    .setTarget(temporalServerAddress).build());
            RegisterNamespaceRequest request =
                    RegisterNamespaceRequest.newBuilder()
                            .setNamespace(namespace)
                            .setWorkflowExecutionRetentionPeriod(Durations.fromDays(31))
                            .build();
            RegisterNamespaceResponse response = service.blockingStub().registerNamespace(request);    

```

Currently the max retention days allowed by the server is 30 days.

This is defined as a [constant](https://github.com/temporalio/temporal/blob/5d924f47b8e8a2f91375f53728077b451464e1e7/common/constants.go#L99). The only way to change that is to update the constant and rebuild your own binary.  
If you need higher retention, I would recommend to look into setting up Archival.
