Cloud-init seems to be ignoring MAAS signal to keep powered after
commissioning.

** Summary changed:

- [2.0 beta2] Machine power's off after commissioning with 'Allow SSH...' option enabled, when using Trusty as commissioning image.
+ Nodes fail to remain powered after Trusty commission with "Allow SSH" selected

** Also affects: cloud-init

Title:
  [2.0 beta 2] Nodes fail to remain powered after Trusty commission with
  "Allow SSH" selected

Status in cloud-init:
  New
Status in MAAS:
  Incomplete

Bug description:
  Build Version/Date: MAAS 2.0 Beta2
  Environment used for testing: Xenial

  Summary: 
  When commissioning nodes with the "Allow SSH" option selected, at least 50% of nodes fail to remain powered and in "Ready" state

  Steps to Reproduce: 
  Enlist 5+ nodes
  Commission all nodes at once

  Expected result: 
  All nodes Ready and powered

  Actual result:
  50-75% of nodes are Ready but powered off
