dynamic membership modification

What is the proper way of adding and removing nodes at runtime?

There was a commit (https://github.com/corosync/corosync/commit/a358791d5b5b5eaaedeba7eae4f89b0e03807c44) a couple years ago which added support for dynamically adding and removing UDPU members. But it looks like in the current release (2.3.2) this code is gone.

I've been able to add nodes by simply putting them in the corosync.conf and calling `corosync-cfgtool -R`, but this does not work for removing. If I remove a node and issue the reload, corosync-cmapctl and corosync-quorumtool both still show the node.
The goal here is to add and remove members without having to shut corosync down and interrupt any services which are using it.

Thanks
