software_manager: Add --allow-unauthenticated to apt options

Sometimes we might add a repo that has no GPG keys and
still want to install a package from that repo. We need
--allow-unauthenticated to tell APT that we really want to install
it.

avocado.core.remoter: Fix error on exception reference

fabric.network was never imported in avocado.core.remoter,
but fabric.network.NetworkError was referenced in its code,
making the exception to never actually be captured. Let's
fix it.

While at it, let's resolve one complaint of the pycharm
python checker: When importing some module on a try/except
block, make some effort to define the module in case of
failure.

Multiplex doc: attempt to reduce confusion on file format and line nu…

Miscellaneous fixes

Ideally our HTML formatted docs would have toggable line numbers. Since
we don't have that, let's just try to be clearer about the line numbers
not being part of the multiplex file format.

Some tests might require additional cleanups not just after the test,
but after the whole job. This patch adds another message called
"func_at_exit", which can be pushed by the test and will get registered
and called when all tests finish.

The test_status is handled in TestRunner.run_test quite chaotically.
This patch extracts test-related communication into a separate class,
and provides simple abstraction, making it simpler to extend it of
other messages.

It turns out that apt doesn't really handle local installs
graciously as dnf/yum, but thankfully there is a program
named gdebi, shipped in Debian and Ubuntu, that would let
us do that. Use it when available (we can make gdebi a
dependency for the avocado debian package to ensure it'll
always be there).

process.py: CmdError class backward compatibility fix

In the newer CmdError class implementation the __init__() doesn't
have anymore the third non-mandatory argument "additional_text".
But still in the different parts of the source code the
CmdError is used with the third argument. If there is no special
reason behind deleting the "additional_text" then I would suggest
to keep for having the backward compatibility.
(for example got argument amount errors while running particular
libvirt tests which had to raise a CmdError exception)

avocado/core/virt.py: avoid crashing when trying to detect VM IP address

The current code assumes that libvirt will always return information
about the VM in a given format, and also assumes that the VM will have
a NIC, which may not be the case.

This adds better checks if the conditions are not met, skipping the
IP detection feature, instead of crashing.

Together with the asset files, we'll now host the RPM repos at
a couple of OpenShift instances, named after the Avocado Project.

The two main repo files are located at:

 * https://repos-avocadoproject.rhcloud.com/static/avocado-fedora.repo
 * https://repos-avocadoproject.rhcloud.com/static/avocado-el.repo

And they point to the same base URL for individual repositories.
