Rename pause annotation

[pebrc]

common.k8s.elastic.co/pause: "true" is somewhat misleading as it might indicate to users that it pauses the managed containers i.e. the Elasticsearch processes which is of course not the case.

• Let's find a better name. A few ideas:
  • common.k8s.elastic.co/suspend-reconciliation (or pause-reconciliation)
  • common.k8s.elastic.co/freeze (or freeze-config)
  • common.k8s.elastic.co/cordon (maybe problematic as you can cordon k8s nodes as well)
  • common.k8s.elastic.co/lock-config
• Rename and document the new annotation

Another proposal: common.k8s.elastic.co/managed.

Influenced by Google Config Sync which has a similar mechanism with an annotation to start and stop managing an object without deleting it.

+1 for managed but maybe like eck.k8s.elastic.co/managed to make it explicit that they are opting out of ECK management.

Alternatively, eck.k8s.elastic.co/ignore might be simpler.

[thbkrkr]

+1 for eck.k8s.elastic.co/.* instead of common.k8s.elastic.co/.* if we can :]
