The guest image tools do not properly configure a network interface
in the image for layer2. When hipersockets is used, setting the MAC
fails with "Operation not supported". No communication with the
dhcp on the network is possible.
OSA was not affected as layer2 is the default for OSA if nothing is
provided (for hipersockets it's layer3).

Sometimes the autoconfigure_networking.service fails with the following
errors:
/lib/s390-tools/lsznet.raw: line 187: cannot create temp file for
here-document: Permission denied
lsznet.raw: ERROR: sysfs reported 0 CHPIDs instead of expected 8
/sbin/znetconf: line 1302: cannot create temp file for here-document:
Read-only file system
znetconf: Error: No configuration found for device ID 0.0.0004
This happens as the service started too early, even before the local
filesystem is available. Changing the systemd startup order to
start the service after the file system target is reached solves
the issue.

The error occures if the directory '/sys/bus/ccwgroup/' does not
exist (znetconf is checking for that). This directory gets created
when the 'ccwgroup' kernel module is initialized. Therefore the
solution is to ensure that this kernel module is loaded.

Adding Testcases for the functions used by guest-image-tools. The
tests are executed by python and integrated into the py27 and py35
test jobs.
Sometimes the guest image tools call external commands
(like ip, zneconf,...). for this case dummy versions of those
executeables are placed in a faked root directory. The test takes
care of exectuing those commands in this directory, therefore the
dummy (bash) executables are chosen over the real ones.
However those dummy executeables cannot replace mocks where a lot
of assertions can be done. As workaround the dummy executeable just
check if it was called with a certain list of arguments. The test
needs to exactly pass those arguments in order to succeed.
Ideally those tests would be functional tests running on a real
system z envrionement. Doing so we could verify if the real
operations are working as well.

Moving all bash functions into a separate file. This avoids that the
main script gets executed when testing function, as now just this
new function file get be sourced.

This is required in order to move those functions into a separate
file. This file can than be easily used for testing.

Since some of the functions are getting called in subshells. Calling
exit in a subshell just quits the subshell but not the whole
programm. As some of the functions should lead to a programm
termination, a fix is required.
Setting "set -e" ensures that the whole programm is being exited in
such cases.

The guest image tools must be installed inside an operating system
to allow automated network configuration.
* autoconfigure_networking
A systemd service that starts before cloud-init. It groups qeth
devices to network interfaces that can be consumed by Linux.
Therefore all devices listed in /proc/cmdline get configured with
the provided portno in layer2 mode. The format of the data in the
cmdline must be
<devno>,<portno>[,<mac>];
* Setmac
A udev rule and the corresponding script to change the MAC address
of a network interface from within the guests operating system.
This is done along the data provided via /proc/cmdline. The format
of the data in the cmdline must be
<devno>,<portno>,<mac>;
Note: The boot-os-specific-parameters property of a partition is used
to pass in data from Nova into the operation system. This data is
appended to /proc/cmdline.
