Currently, the `force` property of the `source_dc` rebuild option
is lost and `raft_topology_cmd_handler` has no way to know
if it was given or not.
This in turn can cause rebuild to fail, even when `--force`
is set by the user, where it would succeed with gossip
topology changes, based on the source_dc --force semantics.
