Migrate Deployment distribution experiment (#268)
Based on #267 (blocked by) related to #237 ------- **Fixed some smaller issues, like:** * rm one-direction from mutex * make possible to run workers against self-managed clusters * return correct errors on connect **Migrate the Deployment distribution experiment, as the first experiment, to zbchaos.** The experiment was executed and verified via the integration test against a self-managed cluster. I moved the experiment into the `chaos-experiments/camunda-cloud/test/` folder and migrated it, with that approach I was able to execute the experiment with `eze` and running against my self-managed `zell-chaos` zeebe cluster.
