Currently, the cleanup script is using existence of
semanage binary to check if selinux is enabled. However
this is misleading and can lead to problems when selinux
is disabled in a system where the binary exist.
This patch changes the detection logic to use /sys/fs/selinux
directory which is a in-memory filesystem created only when
selinux is really enabled.

As described in the comments inline, on a selinux enabled kernel (such
as a centos build host) you need to have permissions to change the
contexts to those the kernel doesn't understand -- such as when you're
building a fedora image.
For some reason, setfiles has an arbitrary limit of 10 errors before
it stops. I believe we previously had 9 errors (this mean 9
mis-labeled files, which were just waiting to cause problems).
Something changed with F26 setfiles and it started erroring
immediately, which lead to investigation. Infra builds, on
non-selinux Ubuntu kernel's, would not have hit this issue.
This means we need to move this to run with a manual chroot into the
image under restorecon.
I'm really not sure why ironic-agent removes all the selinux tools
from the image, it seems like an over-optimisation (it's been like
that since Id6333ca5d99716ccad75ea1964896acf371fa72a). Keep them so
we can run the relabel.

As described in the comment and associated bugzilla, the behaviour of
setfiles has changed in Fedora 26 to require "-m" situations where
labeled file-systems are mounted below non-labeled file-systems. Our
loopback/chroot system appears to trigger this nicely, leading to a
setfiles call that does nothing without this.

In order to support {CentOS,RHEL}7 for building cloud images we need to
handle the differences in grub packaging from Ubuntu. We also need to
populate the defualt location for cloud images for CentOS builds.

Instead, either use the bash built-in of type to ensure it exists. Since
which is an external dep, things can fail oddly in a constrained
environment.
Also add a dib-lint test for this.

With new block device definition, where content of the image
can be mounted on different partitions, is not enough with
executing setfiles on root directory. Instead of that, expose
all the mountpoints on the image, and apply setfiles on them.

This patch finalizes the block device refactoring. It moves the three
remaining levels (filesystem creation, mount and fstab handling) into
the new python module.
Now it is possible to use any number of disk images, any number of
partitions and used them mounted to different directories.
Notes:
* unmount_dir : modified to only unmount the subdirs mounted by
mount_proc_sys_dev(). dib-block-device unmounts
$TMP_MOUNT_PATH/mnt (see I85e01f3898d3c043071de5fad82307cb091a64a9)

Closes-Bug: #1664924
Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).
The problem with this is that editable/development installs (pip -e)
do *not* install data_files. Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.
data_files is really the wrong thing to use for what are essentially
assets of the program. data_files install works well for things like
config-files, init.d files or dropping documentation files.
By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from. In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].
We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.
Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.
I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.
Unfortunately, this has to move to work with setuptools. You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.
[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do. Essentially for us it's returning
__file__.
