juju show-action-status probably doesn't have the best ordering

[John A Meinel]

Trying to figure out if something succeeded or failed, I was running an action a few times and then checking 'show-action-status'.
However, the output doesn't appear to be sorted in a fashion that is useful:
$ juju show-action-status
actions:
- action: ping
  completed at: 2017-11-15 06:19:05
  id: 476821b2-ec99-4092-8183-a2fc715050be
  status: completed
  unit: netutils/0
- action: ping
  completed at: 2017-11-15 06:23:13
  id: 5d1e263b-0c5e-4768-8677-b8cd7e52adc7
  status: completed
  unit: netutils/0
- action: ping
  completed at: 2017-11-15 06:29:17
  id: a1d5cde0-c21d-400a-8e6f-5dd7ec93a7ef
  status: completed
  unit: netutils/0
- action: ping
  completed at: 2017-11-15 06:20:21
  id: cfa338ae-3c66-4c39-8eb6-1bb7770e80fc
  status: failed
  unit: netutils/0

That doesn't look to be the order that I requested them, nor the order that they completed in.
The last one requested is second from the end.

It looks like they are actually sorted by "id" but I think that doesn't actually mean anything to anyone. Its intentionally an *opaque* UUID.

I think sorting by time might make the most sense.
