FEAT 60430: Add ability for wait_for_event to handle list event_id values

[jwyoungpm]

What does this PR do?

Adds support for comparing id_list with a list when the value for event_id is a list in the salt.wait_for_event module.

What issues does this PR fix or reference?

Fixes #60430

Previous Behavior

Previously, salt.wait_for_event only supported event_id values that where str.

New Behavior

In addition to the previous behavior, now supports event_id values that are lists.

Given the event:

{
   "data": {
      "new": [], 
      "lost": [
         "some_old_node"
      ], 
      "_stamp': '2021-06-23T15:02:04.621354"
     }, 
     "tag": "salt/presence/change"
}

the following salt.wait_for_event would not work peviously:

wait-for-node-death:
  salt.wait_for_event:
    - name: salt/presence/change
    - id_list:
       - some_old_node
    - timeout: 3000
    - event_id: lost

This PR checks if the val returned by the event_id location in the event is a list and if so, pops off any values from id_list that it finds in val

Merge requirements satisfied?

[NOTICE] Bug fixes or features added to Salt require tests.

• Docs - Docs do not diferentiate between value types returned by event_id so I did not update
• Changelog - https://docs.saltstack.com/en/master/topics/development/changelog.html
• Tests written/updated

@krionbsd sorry I haven't come back and checked on this, out on paternity :)

Could someone have a look at this? Let me know if there are any blockers to merging.

@krionbsd @s0undt3ch Sorry for the very late follow up on this...I got back from paternity leave not long ago, I believe this is still a valid MR. Is this still something I could get merged? You both have approved but I can't click the merge button.

Thanks!
