The fingerprint must be static across executions, but TreeEnvironment is
simple unsorted dictionary. Let's sort it on demand (usually only for
fingerprint).

Currently, the only way to pass parameters to Avocado is by using the
variants layer, that is, one of the existing varianter plugin
implementations.  This was based on earlier design decisions, that
we're trying to fix without breaking expectation and compatibility.

While it'd makes sense to support parameters created by the varianter
layer itself, together with non-varianter parameters, it seems that we
can start by adding support for one or the other being used at a time.

This commit does exactly that: add support for a method of passing
parameters via the command line for all tests in a job, without
having to resort to the varianter.  When the varianter is used,
it takes precedence and the core test parameter passing support
is ignored.

This should solve a number of use cases that require one-time
executions of tests with different parameters, especially
executions during test development and debugging.

The lv_utils functional tests, which usually don't run because
they require privileged execution, revealed a number of broken
expectations when it comes to bytes and text handling.

Let's fix both the module and the test.

When running privileged, MixInMntDir requires the "mixed in class" to
adhere to some expectations, including having a `path` attribute, and
unmounting the filesystem on `close()`.

It looks like this wasn't properly tested because of the seldom (if
any) privileged executions.

This implements a connection wrapper around SSH, and requires the
OpenSSH client tools installed.

It uses a master connection for a number of reasons, including but not
limited to being able to distinguish between connection failures and
command execution failures.

Most of the command execution results are accurate and similar to
users of `avocado.utils.process.run()`: the exit status is preserved
for the local user inspection.  The stdout and stderr, time taken to
execute the command (including the remote part) is also available.

This change focus mostly on increasing tests for VmImageHtmlParser and
ImageProviderBase. During the tests implementation some improvements
were detected: the process of feed a html parser run both for get an
image version and image url was duplicated so it was unified in a single
method.

Besides that the process of get a best version for an image was put on a
specific method so each provider can override it if required. Today the
default rule for a best version is based on calling max() function on
found versions. However we can't assume it's the default for every
provider. As far as we know, for a possible OpenSuse provider in future
this rule will not be valid.

This change makes possible to call kill_process_tree() function with
pid of sudo enabled processes and it also makes possible handle timeout of
subprocesses called with sudo=True.

Both cases now use a new function created in process module to return
the user owner id of a pid (get_owner_id).

For the case of subprocesses run with sudo=True it was necessary adjust
the send_signal() method of SubProcess class so it can send the signal
for sudo process child.
