[Bug 1463373] Re: cc_apt_configure does not work with python3

[Scott Moser]

recreates easily enough:

$ python3 -c 'from cloudinit.config.cc_apt_configure import getkeybyid; import sys; getkeybyid(sys.argv[1], sys.argv[2])' 03683F77 keyserver.ubuntu.com
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/cloudinit/config/cc_apt_configure.py", line 113, in getkeybyid
    fh.write(EXPORT_GPG_KEYID)
  File "/usr/lib/python3.4/tempfile.py", line 556, in func_wrapper
    return func(*args, **kwargs)
TypeError: 'str' does not support the buffer interface

Fixes like this:
$ ( cd /usr/lib/python3/dist-packages/ && diff -u cloudinit/config/cc_apt_configure.py.dist  cloudinit/config/cc_apt_configure.py )
