The loguserdata.py file gets uploaded to the servers created by Heat to run
under cloud-init. Since the default versions of Python installed on the
user's server may be very old (e.g. RHEL 5 defaults to Python 2.4), avoid
using the octal syntax introduced for Python 3.0 and backported only as far
as Python 2.6. (Also avoid the old syntax, which will break on Python 3.x.)
Also remove use of the "with" statement from loguserdata.py and
part-handler.py. This statement is only available from Python 2.6 on (or in
Python 2.5 via "from __future__ import with_statement").
Finally, remove use of the "except ExceptionType as value" syntax for
catching exceptions. Again, this was only backported to Python 2.6.

Partial-Bug: #1375864
Ubuntu has 0.6 of cloudinit, and write-files doesn't work on that
distro. Ubuntu does not intend to update cloudinit in their LTS release
to 0.7.
This reverts commit 621f5bfdba.
Fixes: Bug #1207088
Change-Id: If80863883afee28bdde6dd506826ec5710cc0308
part-handler.py was acting as a write-files mechanism. Instead just
use the write-files mechanism directly to avoid the complexities of
the part-handler.
