[PATCH 00/16] Acceptance Tests: use Avocado 91.0 features and other improvements

[Cleber Rosa]

This is a collection of patches for the Acceptance Tests to leverage
some of the features of Avocado 91.0.  With the Avocado version bump
by itself, there would be a change in the default "test runner"
implementation that Avocado uses, from the one simply known as
"runner" to the new one called "nrunner".

Among the changes from one implementation to the other, is the fact
that "nrunner" will run tests in parallel by default.  This is *not
yet* enabled by default on "make check-acceptance", but users can
choose to use simply by setting the "AVOCADO_RUNNER" variable, that
is:

  make AVOCADO_RUNNER=nrunner check-acceptance

If you are curious about the architectural differences of the nrunner,
please refer to:

  
https://avocado-framework.readthedocs.io/en/91.0/guides/contributor/chapters/runners.html

One other noteworthy proposal is a convention to tag tests that either
have known issues, or that touch on QEMU features that have known
issues.  By tagging those tests accordingly, they will be
automatically excluded from the regular execution with "make
check-acceptance".

Finally, some updates to assets locations and some tests refactors and
cleanups.
