When the pod is scheduled to another node, it should be able to join back the quorum.
Actual behavior
The MySQL unit fails to join back the quorum, complaining about An instance with label 'squirrel-mysql-0' is already part of this InnoDB cluster

Additional context
This is part of a work in Sunbeam to be able to remove a node being part of a k8s cluster. Mysql units might be hosted on there, and we should be able to re-schedule them to other nodes.
The reproduction script is a bit convoluted, but this actually resembles a sunbeam installation.
Steps to reproduce
Expected behavior
When the pod is scheduled to another node, it should be able to join back the quorum.
Actual behavior
The MySQL unit fails to join back the quorum, complaining about
