Description

Currently it’s only possible to move tokens on nodes with single tokens, but the protocol introduced on CASSANDRA-16139 makes this a possibility on nodes with multiple tokens.

This may be useful to perform ring rebalancing operations. A pseudo-code for the move token operation is available here.

This ticket is to enable this functionality to users via ringtool (CASSANDRA-16140).
