Prior to the change in #51631 indices were moved to the TerminalPolicyStep when their ILM actions
had completed. Once we switched ILM to stop in the last policy configured, these steps because
inaccessible from the policy's perspective. This meant that indices upgraded from ES prior to 7.7.0
could see the following error spammed in their logs every 10 minutes (by default) for every index in
this state:

[2020-04-14T15:52:23,764][ERROR][o.e.x.i.IndexLifecycleRunner] [midgar] current step [{"phase":"completed","action":"completed","name":"completed"}] for index [foo] with policy [full] is not recognized

This changes the runner to ignore these steps, which is what is desired anyway since the index is
already in the terminal phase.
