VertxWebSocket throws RejectedExecutionException after the client has shut down

[cowwoc]

Describe the bug

I am getting this RejectedExecutionException intermittently after the client is shut down.

You'll probably need to do the same as #6063 for this case

Fabric8 Kubernetes Client version

7.0.1

Steps to reproduce

Not sure

Expected behavior

Closing the client should shut down all dependent watchers

Runtime

Kubernetes (vanilla)

Kubernetes API Server version

1.25.3@latest

Environment

Windows
