Multiple output plugins

Some brief documentation on the JSON output plugin and
multiple output plugins.

Add extra tests that verify that the always on output
plugins (JSON and Xunit inside the debug dir) are being
correctly generated and the outputs are valid.
Signed-off-by: NLucas Meneghel Rodrigues <lmr@redhat.com>

As specified in the requirements meeting, always have Xunit and
JSON outputs written to the results dir. The basic idea is to
enable any output plugins specified in the cmd line, the Xunit
and JSON compulsorily, and in the end, if there are no output
plugins requested in the command line, enable human output.

It's necessary if we're generating valid outputs in

With the new attributes, change the output setup procedure
to verify if more than one output plugin wants to use the
stdout, in which case we print an error message and fail.
Signed-off-by: NLucas Meneghel Rodrigues <lmr@redhat.com>

In order to be able to tell whether there's more than one
output plugin trying to use the stdout, add the 'output'
and 'output_option' attributes. This changes the current
output plugins to use and set these attributes correctly.

Fix the xunit unittest to take into account the new
attribute names.

Set up the TestResultProxy for the Job object, and
populate the test result objects according to what
the currently active plugins set. This means we go
on finding arguments with the suffix _result and
selecting any values that are classes derived from
TestResult and appending them to the result proxy.

With this, we can use any number of test result
plugins we'd like. If no test result objects are
set by plugins, fall back to the human output plugin.
Signed-off-by: NLucas Meneghel Rodrigues <lmr@redhat.com>

Create a class that has the same interface as a
test result, but in fact has a list of test result
objects and can write to each of them any time
a test result operation is called. This is the
first step to make multiple output plugins to
work.

Add a timeout test module for avocado, to exercise the
test timeout functionality. This test is supposed to
fail by timeout.
Signed-off-by: NLucas Meneghel Rodrigues <lmr@redhat.com>

In order to ensure avocado tests won't mess with the
main avocado process' environment, execute them in
forked subprocesses. If the test params have a
'timeout' attribute, use it as the timeout param
of the .join() multiprocess method, allowing the
subprocesses to be killed after timeout seconds if
they did not complete.
