Move LastUpdated property on the LRP CR from its Spec object to the Status object

Also, LastUpdated should be automatically set by the LRP controller on update rather than allowing users to do that via manual updates.

It is not quite clear what this property is expected to be used for in the K8S world.
In the VM world, CC would send the value upon LRP updates (i.e. when CC calls the Update endpoint). We suspect that this is needed to verify whether the version of the LRP in the CC database matches the one that is actually running.

In K8S world this consistency is ensured by controllers so we do not need a special field. It feels like we could just get rid of the field in our custom resources but let's talk about it on standup.
