Hey are there instructions anywhere for manually removing a control plane node? We have 2 cp/etcd (5 total, 3 healthy) nodes that are in a bad state of some kind and the instructions say to remove them...but they won't remove. Rancher just stalls at "removing member [etcd-blah-m3]". I think this may have happened because we tried to add and remove cp 1 cp node at the same time. In one screen Rancher says that it's waiting for the new one to provision, in the provision log, its saying its waiting for the removed one to be removed. I've removed the one it was waiting to provision but it's just continuing to wait for the non-existing none to provision.
