(bulk) replacement for Ganeti's own *gnt-node evacuate*, with the
note that it doesn't guarantee full evacuation.
This parameter disallows any replace-primary moves (frf), as well as
those replace-and-failover moves (rf) where the primary node of the
instance is not drained. If used together with the ``--evac-mode``
option, the only migrations that hbal will do are migrations of
instances off a drained node. This can be useful if during a reinstall
of the base operating system migration is only possible from the old
OS to the new OS.
This parameter marks the given instances (as a comma-separated list)
as the only ones being moved during the rebalance.
