> Currently, we can test range movements only by adding and bootstrapping a new 
> node. This is both inefficient and insufficient for large-scale tests. We 
> need a possibility to dynamically change ring ownership over the lifetime of 
> cluster, with a flexibility to changing gossip status of the node from 
> perspective of other participants, adding and removing nodes from other 
> nodes' views on demand.
