[ILM] Delete phase can be created without delete action (empty actions object)

2

yuliacech commented Dec 3, 2020

Currently, it's possible to create an ILM policy with a Delete phase with an empty actions object so that the phase doesn't contain a delete action. This will result in a policy that will not delete indices.
How to reproduce:

PUT _ilm/policy/my_policy
{
  "policy": {
    "phases": {
      "delete": {
        "actions": {}
      }
    }
  }
}
