This will instruct all JVMs (including any that run cli tools such as creating the keyring or adding users)
to suspend and initiate a debug connection on port incrementing from `5005`.
As such the IDE needs to be instructed to listen for connections on this port.

`system:aggregate-to-edit` role no longer includes write access to the Endpoints API. For new Kubernetes 1.22 clusters, the `edit` and `admin` roles will no longer include that access in newly created Kubernetes 1.22 clusters. This will have no affect on existing clusters upgrading to Kubernetes 1.22. To retain write access to Endpoints in the aggregated `edit` and `admin` roles for newly created 1.22 clusters, refer to https://github.com/kubernetes/website/pull/29025.
