The getSystemMetadata method doesn't have the replicas info

[taojing2002]

When I tried to get the system metadata for an object the with replica info , the system metadata doesn't include the replica information part such as node id, status and verified date. But it includes the replication policy part.

This is a really shortcoming of the datapack::SystemMetadata class, which does not store or represent the replica information. See https://github.com/ropensci/datapack/blob/main/R/SystemMetadata.R#L89. Part of the reasoning for this is that replica information comes from the CN, whereas the system metadata is often coming from the client or member repo, and so we didn't want to make extra call to get replica info. But I agree that, given a sysmeta with replica info, we should represent it and make it accessible.

As a workaround, the replication information is available from CNode::resolve().
