Cluster.name (and other _cluster_info items) get carried over to subsequent Clusters

( if Cluster.__init__ is not called before Cluster.name.__set__ )

import sys

from distributed.deploy import Cluster

class ExampleCluster(Cluster):
    def __init__(self, name, *args, **kwargs):
        self.name = f"example-cluster-{name}"
        super().__init__(*args, **kwargs)


def main():

    print(
        Cluster()
    )  # Cluster(e174b1b2, '<Not Connected>', workers=0, threads=0, memory=0 B)
    print(
        ExampleCluster("demo")
    )  # ExampleCluster(example-cluster-demo, '<Not Connected>', workers=0, threads=0, memory=0 B)
    print(
        Cluster()
    )  # Cluster(example-cluster-demo, '<Not Connected>', workers=0, threads=0, memory=0 B)
    return 0


if __name__ == "__main__":
    sys.exit(main())

I'm curious, what was the context here? Where did this come up?
