Description

The logical here to remove endpoints no longer owning tokens is not working for multiple tokens (vnode):
https://github.com/apache/cassandra/blob/06209037ea56b5a2a49615a99f1542d6ea1b2947/src/java/org/apache/cassandra/service/StorageService.java#L2505

And it's very expensive to copy the tokenmetadata for every check.
