Title:
  Allow for merging with json-patch

Status in Init scripts for use on cloud images:
  Fix Released

Bug description:
  It would be pretty nice to allow for merging using the json patch
  specification.

  https://tools.ietf.org/html/rfc6902
  (https://tools.ietf.org/html/rfc6902#page-4)

  Said specification provides a common way to add/remove/delete when
  patching:

  '''
     This format is also potentially useful in other cases in which it is
     necessary to make partial updates to a JSON document or to a data
     structure that has similar constraints (i.e., they can be serialized
     as an object or an array using the JSON grammar).
  '''

  Since cloud-inits cloud-config is yaml (but could just as easily be
  json), the above seems pretty applicable to the type of updates
  (merging) that cloud-init performs. To start it might be neat to allow
  for a new mime-type that #json-patch where these types of merging
  operations happen.

  https://pypi.python.org/pypi/jsonpatch/0.6 exists and seems like its
  being actively developed and it will likely make applying the
  specification much easier to do.
