Avoid dangerous file parsing and object serialization libraries.
yaml.load is the obvious function to use but it is dangerous[1]
Because yaml.load return Python object may be dangerous if you
receive a YAML document from an untrusted source such as the
Internet. The function yaml.safe_load limits this ability to
simple Python objects like integers or lists.
In addition, Bandit flags yaml.load() as security risk so replace
all occurrences with yaml.safe_load(). Thus I replace yaml.load()
with yaml.safe_load()

As described in the bug, there are conditions with certain switches
in which the interface is 'admin down'ed during initialization.
Doing a 'cat' on /sys/class/net/<interface>/carrier when it is
'admin down'ed produces an 'Invalid Argument' error and the script
terminates. What this fix does is ignore failures of the 'cat'
operation (by '|| echo 0') and place the link up inside the retry
loop.

Xenial's bind of /dev into the chroot includes /dev/shm which is in
use by the host. An alternitive fix for this would be to use rbind
to recursivly bind mount /dev instead of just the base bind of /dev

As noted in the bug, there may be circumstances where a longer
timeout than the current default is needed. This patch allows users
to tune this timeout for their environment if need be.

When we configure dhcp interfaces before network.target has run,
network.target will try to bring up those interfaces a second time
after our service does so. This causes two issues - first, the
network target will always fail because it can't bring up an
interface that is already up, and second, when configuring interfaces
that don't actually have an available DHCP server it will result in
a five minute delay waiting for DHCP on those interfaces. This will
also cause the network target to fail and is an unnecessary delay.
By moving the dhcp-interface service to run after the network
target we avoid both of these problems. network.target will still
bring up the interfaces on subsequent boots. This could result in
the five minute delay happening on reboots, but the expected use
case for interfaces without DHCP is that they would be configured
statically on initial deployment so this should be a minor issue.
The dhcp-interface service is also configured to run before the
network-online target so that services which depend on the network
actually being available will not race the DHCP process.
A snippet from /var/log/messages on a node with this patch applied
is included in the bug to demonstrate the behavior described above.

There are issues with pip packages and a python3 only Xenial systems.
This is occuring after Ie609de51cc5fcde701296c9474e315981d9778a2.
We believe the issue is with VIRTUAL_ENV being set within the chroot
and messing up pip installs
(Icdb769541eee9793f261b4b8ec563be76ee13fe2) but a full solution is not
yet clear.
For now, set Xenial to ensure we use python2. Install the package for
the ubuntu element (75-debian-minimal-baseinstall will install python2
for the minimal elements).

Since we still run these 3 version of ubuntu-minimal elements in
openstack-infra, also run functional testing for them.
Trusty and xenial will be in voting gate, precise added as skipped for

Add the default skip/run status to the "-l" output just to confirm
this too.

Every run we are doing a full tar.gz of the chroot environment that
never gets used.
It's not suitable for CI since we use fresh images each time there.
The cache in general isn't really isn't a very safe thing to have
around, because there's no invalidation procedure and no real way to
make one -- we've no guarantee that a new chroot build even moments
after a previous one wouldn't bring in or different packages, etc (of
course this is *unlikely*, but the longer you go between builds the
worse the problem becomes. Also, tons of packages get installed after
this not from any cache, so potential speed-up is rather marginal.
Debian turned this off with I58fc485aacacaa17243bf9ce760ed91256d1f182.
However, given the reasons above and it's complete lack of testing, I
don't see this as useful.
If we really want this type of thing, I think we should come up with a
way to use a persistent external yum/dnf cache that yum/dnf keeps in
sync with it's usual invalidation rules.

Set the grub timeout to 5 seconds by default, and add notes on how to
update this. This will stop infra having to carry an element that
goes and rewrites the grub configuration.

dracut has a "hostonly" mode where it builds an initramfs that is
suitable for booting the system it is building on. This is on by
default, but obviously in our nested multi-platform chroot situation
this is fraught with danger.
As highlighted by [1] our builds were inadvertently turning off
"hostonly" mode when the mountpoints in the chroot were not found.
The CentOS 7.3 behaviour change broke this and we ended up with an
initramfs with no file-system modules.
Iaf2a1e8470f642bfaaaad3f9b7f26cfc8cc445c9 introduced a regeneration of
the initramfs, which I think does work as described because it runs in
the loopback device.
However, dracut includes a package that installs configuration
overrides to build a generic initramfs. This is really what we want,
and should solve the problem no matter where the initramfs is created.
Add this package into yum-minimal and remove the extra re-create call
which should not be necessary.

openSUSE 13.1 was discontinued on Feb 3rd, 2016, so defaulting
to it doesn't make sense (see https://en.opensuse.org/Lifetime).
Leap 42.2 is the most current release that is supported by
disk-image-builder and being tested in a 3rd party ci.
Enable functests for it to ensure we're not regressing again.

For some reason [1] introduced -m option without ever checking that the
mapping exists. Because there is no grub-ieee1275 mapping anywhere (not
in base, not in bootloader), pkg-map fails. So stop using the mapping in
package-install of grub-ieee1275 on ppc.
There is another patch that tries to solve the same bug by adding the
mapping [2]. I think it is better to undo the breakage introduced in [1]
first, and then, if various distributions have differing names for the
package, introduce various mappings. My reasoning is that at the moment
this element is broken for all ppc64 distributions. This patch would
fix it for some (namely, Ubuntu). Then we can add mappings as tests
are done for other distributions.

dracut has a loop [1] where it probes top-level directories, tries to
find what block device they are on, then determines the file-system of
that block device. It then puts those file-system modules into the
initramfs for boot.
Since we install the kernel package during the chroot phase, / there
is not a block device and thus this loop matches nothing and we end up
with no file-system modules in the initramfs. This results in a very
annoying silent boot hang.
By moving re-generation of dracut into finalise.d phase, we run inside
the final image where / is the loop-device; the root file-system gets
detected correctly and the ext4 module is included correctly.

Tripleo-image-elements have an install.d file '05-heat-cfntools' that runs
the following command:
virtualenv --setuptools $VENV
With the recent change to diskimage-builder (moving the install of pip
and virtualenv to the 10- range) virtualenv is no longer available for
this elementr; as a side-effect, the trove kick-start command is now
broken and gate jobs are failing.
The solutions is to move the (now) 10-install-pip to 04-install-pip.
This should still alleviate the race condition that
https://review.openstack.org/#/c/408277/ attempted to fix, as all
*-package-installs files are 00-, 01- or 02-.

Commit 6278371eaa13("Make dib-python use the default python for distro")
added default python version for various distros but it missed openSUSE
which leads to build failures since the openSUSE elements are pulling
python2 packages. Add openSUSE to the list of python2 distributions
until python3 support for the openSUSE elements is in place.

Now that we are explicit about what python version we intend to use
for dib we can have package installs optionally install packages
depending on this. Add a new dib_python_version that matches on the
DIB_PYTHON_VERSION string set by dib-python.
