CLI (and SDK) Unnecessary yaml rewrites

[Maxusmusti]

Currently, when calling using the CLI's status or details commands, they will also write the cluster's AW back to current dir, since get_cluster() recreates the Cluster object. Perhaps we should have a Cluster creation option that doesn't actually generate the AW (just stores values in cluster/config object memory)? That way it can get consumed by get_cluster() optionally, and the CLI can then use that.
