drain module should not warn, or have a nowarn, when user requested the action

[smemsh]

SUMMARY

Drain module should have an option to disable warnings about things that were explicitly requested by the user.

ISSUE TYPE

• Feature Idea

COMPONENT NAME

k8s_drain

ADDITIONAL INFORMATION

These warnings are tautological, because the user has already had to provide a non-default option to request the action, so it warns about something that is expected. I would argue they should default to off anyways or be removed, but it's debatable. At least an option would be good. For example this makes little sense:

kubernetes.core.k8s_drain:
  ...
  delete_options:
    ignore_daemonsets: true
    delete_emptydir_data: true

gets the result:

[WARNING]: Deleting Pods with local storage: kube-system/cilium-cst6l.
[WARNING]: Ignoring DaemonSet-managed Pods: kube-system/cilium-envoy-wcpd6.

I have specifically requested these things, yet it warns me. Ok maybe for verbose safety purpose, but not for ordinary operation, at least have a warn boolean. Although kubectl warns about this, I find that silly too, at least allow to suppress these in the ansible module so the tooling output is not polluted.

Note: action warnings can be suppressed in ansible.cfg or in environment, but only on a global basis, so this is best implemented as module arguments.
