This commits adds initial support to build Vagrant boxes with the Virtualbox
provider.
- The attribute 'provider' of the option <vagrantconfig> now supports the option
"virtualbox".
- A new boolean attribute 'virtualbox_guest_additions_present' was added to
<vagrantconfig>. When set to true, KIWI will assume that guest additions have
been installed into the base image and configure the shared folders to use
vboxfs, otherwise rsync will be used.
This fixes#532 (https://github.com/SUSE/kiwi/issues/532).
YUM v3 is no longer developed, having been superseded by DNF for
several years. With DNF now available as a usable package manager
in Red Hat Enterprise Linux 7 through the Extras channel and
SUSE Linux Enterprise 15 through PackageHub, there is no reason for
keeping support for YUM v3 around.
We are keeping support for requesting YUM because in Red Hat Enterprise
Linux 7, DNF is referred to as "YUM v4", and it is simply referred to
as "YUM" in Red Hat Enterprise Linux 8. To avoid confusion from people,
we're just going to leave it in place as an alias to the DNF package
manager.
As for why this is happening now, Fedora is retiring YUM v3 in
Fedora 31, so we might as well get it over with and cut over now.

In preparation to support other vagrant providers a base class
for Vagrant operations has been created. Original Code written

- fix CLI args not being passed to pytest by tox for unit_py3_4 and unit_py3_6
- enable parallel run on travis
- document how to run the unit tests in parallel
Updates the information about how /etc/machine-id is treated in KIWI
and provides some hints for old systems where /var/lib/dbus/machine-id
is not a symlink to /etc/machine-id
