Title:
  cc_apt_configure does not work with python3

Status in Init scripts for use on cloud images:

Status in cloud-init package in Ubuntu:

Status in cloud-init source package in Vivid:
  Confirmed
Status in cloud-init source package in Wily:
  Confirmed

Bug description:
  The way cc_apt_configure.py writes out the script to fetch GPG keys
  breaks when using Python 3.

  * There's a constant, http://bazaar.launchpad.net/~cloud-init-dev
  /cloud-init/trunk/view/head:/cloudinit/config/cc_apt_configure.py#L39
  that contains the script.

  * In getkeybyid, it's written to a temporary file:
  http://bazaar.launchpad.net/~cloud-init-dev/cloud-
  init/trunk/view/head:/cloudinit/config/cc_apt_configure.py#L113

  Python 3 throws an exception: 'str' does not support the buffer
  interface when doing the write.

  A very simple example:

  import tempfile

  fh = tempfile.NamedTemporaryFile()
  TEST_STR = """ HELLO WORLD """
  fh.write(TEST_STR)

  Will work with 2, but not 3.
