avocado.core.multiplexer: Assign tag to match multiplex variant

We're bringing new code, and with it, new deps.
Signed-off-by: NLucas Meneghel Rodrigues <lmr@redhat.com>

"avocado multiplex" and "avocado run" should share the same variant
numbers. This patch forces multiplexer to set the tag when generating
multiple variants. This way the tag is always set accordingly to the
variant.

When multiple tests of the same name are executed, the first argument is
the multiplexed variant number and additional `.$num` is added to
generate unique name.

After testing the use of those APIs, I realized that
having the entire stdout/err of the commands executed
was pretty overkill and potentially confusing, so I've
turn on the flag verbose=False for certain process.system

Add the possibility of using caching in the get_file
API -> If the dst already exists, we can compare its
file hash (SHA1, MD5, among others) with an expected
hash. If the hashes match, don't try to retrieve the
src again, just return.

Revert "avocado.core.multiplexer: Assign tag to match multiplex variant"

This reverts commit 913ab2ab.

Turns out that change appends inconditionally the tags to tests,
even the ones not using the multiplexing system. We need to revert
and figure a better solution.

The test log compounds of "avocado.test" and the "$ROOT" logger. We must

Due to successive refactors in the test runner mechanism,
we did not notice that our Ctrl+C handling during job
execution went south. This patch fixes it by moving the
interruption handling to a place where we can actually
break free from the test looping. I also made the interrupt
messages cleaner, while keeping them informative.

The behavior "don't kill test subprocesses unless the user
really wants it" was also kept. You can test this by
running the multiplex test (large collection of tests):

[V2] avocado: Shorter app output

avocado.utils.astring: Improve the tabular_output

This patch doesn't generate the trailing whitespaces rather then
removing them from the output afterwards, which was potentially
dangerous as the line might start with the whitespace and got displaced.
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

Instead of putting outputs on separate lines, condensate
test results summary into a single line. The new output
looks like:

$ avocado run passtest

We updated a few unittests in order to not depend on the
looks of the human output anymore, since unless we are
specifically testing for human output behavior, the unittests
should use machine readable output. Also, the documentation
was updated to reflect the new output layout.

Use the new iter_tabular_output generator in the
avocado listing related commands, since displaying
each line of the iterator is already what we want
in the avocado listing commands.
Signed-off-by: NLucas Meneghel Rodrigues <lmr@redhat.com>

We did notice that listing commands have trailing whitespace
at their ends. Trailing whitespaces are bad for program output
(copy/paste, among other reasons), so let's fix it.

I did notice there was no reason to not implement the base
function for the tabular output as a generator, so I've
introduced iter_tabular_output, that is a generator, and
in order to not break API unnecessarily, implemented
tabular_output in terms of iter_tabular_output.

This is a rather embarassing bug. We should be testing
for equality of outputs, so assertEqual instead of
assertTrue (which in effect makes the test always pass,
regardless of the avocado output). Let's fix it.
