cloud-init --local needs mounted /run but not guaranteed by upstart job

[Scott Moser]

in cloud-init local , cloud-init does:
 a. create /run/cloud-init if it does not exist
 b. write some data to /var/lib/cloud/data/status.json
 c. link /run/cloud-init/status.json

if /run is mounted over the top of /run between a and c, then we'll fail to create the symlink,
and will have a stack trace to console like:
Traceback (most recent call last):
  File "/usr/bin/cloud-init", line 618, in <module>
    sys.exit(main())
  File "/usr/bin/cloud-init", line 614, in main
    get_uptime=True, func=functor, args=(name, args))
  File "/usr/lib/python2.7/dist-packages/cloudinit/util.py", line 1875, in log_time
    ret = func(*args, **kwargs)
  File "/usr/bin/cloud-init", line 491, in status_wrapper
    force=True)
  File "/usr/lib/python2.7/dist-packages/cloudinit/util.py", line 1402, in sym_link
    os.symlink(source, link)
