K8S Cluster Name

[simonmacklin]

Would you accept a PR to allow a user to add the cluster name to be added to each of the events.

This is handy when you have many clusters and don't want multiple channels. If this is something you would accept I can work in the PR.

Thanks

hey @simonmacklin

We'd love to accept such a PR.
Please make it backward compatible, so that the new behavior won't affect existing users, unless they explicitly choose to use it
