Avocado selftest supports parallel check, enabled by the env. variable
`AVOCADO_PARALLEL_CHECK`. Let's enable that in travis so big PRs will
have a better change to finish before the travis 50min timeout.

All other result plugins write (by default) to the job results dir.
The HTML plugin was different because it used to require a number of
files.  Now, it's a single file, and thus, could/should live in the
same place as other files.

To ease the transition of the location, let's add a symlink, so that
users can still rely on the old location.

Words like JSON and YAML are acronyms, and should be written
using capital letters only.
Signed-off-by: NCleber Rosa <crosa@redhat.com>

The yaml_to_mux plugin may be able to read JSON files, but this not
documented *at all* and conflicts even with the basic help information
given on yaml_to_mux.  Let's omit that until we decide if JSON should
be treated by Avocado as a valid input to yaml_to_mux.

Then, while at it, a hopefully clearer version, broken down into
smaller sentences, is being proposed.

Each test executed in Avocado gets its own process.  But, there are a
few peculiarities that test writers may have to deal with, so let's

When Varianter plugins report no variants, default is provided by
Varianter on `itertests`. The same needs to be emulated in case of
`to_str`, otherwise users would not get the same results as during
`run`.

Currently there are two types of plugin names, one is the fully
qualified plugin name, which is the namespace used by stevedore and the
other is the module name, which is the module which handles the code.
It's probably too late to adjust the behavior, but let's at least
provide correct examples to simplify the usage.
