Bug description:
  === Begin SRU Template ===
  [Impact]
  Unit tests for cloud-init did not run successfully in a centos environment.
  This is really just failure of the unit tests.

  The fix was to no longer expect /sbin/mkfs.ext4 but to mock the
  checking.

  [Test Case]
  Test of ubuntu package in centos is non-trivial and/or not useful.
  The proposed test case is to just run the trunk tests at the
  uploaded git commit in a lxc container (the environment that originally
  found the issue).

  $ lxc launch images:centos/7 c7
  $ sleep 10; # let it boot
  $ lxc exec c7 -- /bin/sh -xe <<"EOF"
  yum install --assumeyes epel-release
  yum install --assumeyes pyserial python-argparse python-cheetah python-configobj python-jinja2 python-jsonpatch python-oauthlib python-prettytable python-requests python-six python-pip PyYAML git file e2fsprogs
  pip install contextlib2 httpretty mock nose pep8 unittest2
  git clone https://git.launchpad.net/cloud-init
  cd cloud-init
  git checkout 16a7302f
  nosetests tests/unittests
  EOF

  [Regression Potential]
  No runtime regression potential.
  Unit test only changes.

  [Other Info]
  Upstream commit at
    https://git.launchpad.net/cloud-init/commit/?id=951863c21

  === End SRU Template ===

  A recent merge that added a mkfs.ext4 tests has a hard coded location
  for the binary of mkfs.ext4. The result is that on centos 7, which has
  the command in a different location than Ubuntu, is a failed test:

  https://paste.ubuntu.com/24589593/

  Steps to reproduce:
  lxc launch images:centos/7 c7
  lxc exec c7 bash
  yum install --assumeyes epel-release
  yum install --assumeyes pyserial python-argparse python-cheetah python-configobj python-jinja2 python-jsonpatch python-oauthlib python-prettytable python-requests python-six python-pip PyYAML git file e2fsprogs
  pip install contextlib2 httpretty mock nose pep8 unittest2
  git clone https://git.launchpad.net/cloud-init
  cd cloud-init
  nosetests tests/unittests
