This way we work similarly as to when we develop
avocado-virt, which is in fact very convenient.

Some upcoming test sources may want to simply append
multiplexer params to their original params, instead
of having them overwritten by avocado. Let's Define a
mechanism to do that. Test sources, as they assemble
the params that will be used with the test classes, may
define the key avocado_inject_params and set it to True.

If the avocado finds out about that param, it will append
the avocado specific params in the param 'avocado_params',
making it possible for said upcoming test classes to
retrieve avocado specific params.

The last refactor allowed us to move loader specific info to test
loader plugins. This will allow new test loader plugins to add
new information about how to classify/find new tests, in a way
that we can list new tests without having to modify the test
lister plugin.

We did modify the test lister to list the extra test sources,
and also made it a priority 0 plugin, to ensure extra test
sources plugins get loaded after it, effectively preventing
errors like:

AttributeError: 'Namespace' object has no attribute 'vt_list_guests'

Allow multiple plugins to implement a TestLoader class
that will allow avocado to understand new types of tests.
The url list will be passed through available test loaders,
that will see if they can handle it, if they can't, they pass
to the next one until we find out one loader that can take
care of the job.

avocado.core: Internal attribute to take_action() is now 'dispatch'.

There is a great difference between filter path ending with slash or

avocado.multiplexer: Use !mux and support for recursive mux [v3]

This patch adds documentation of the "new params API" and removes the
compatility layer. From now on only the API with paths is valid:

    self.params.get(key, path='*', default=None)

where the default path '*' matches anything from --mux-entry path.
Default path is `/test`.
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

This patch modifies all example tests to use the new API. It uses the
default path, which is `*`, which matches the mux-entry paths ONLY.
In order to get the values it's necessarily to inject the YAML files
into the mux-entry path, by default `/test`, eg:

    avocado run sleeptest -m /test:examples/tests/sleeptest.py.data/
    sleeptest.yaml

It might seen as a bit more complicated to execute, but it's definitely
easier for maintaining and combining existing YAML files. To execute
matrix of tests you simply inject them into 2 different `/test` children,
eg: `-m /test/by_length:lengths.yaml /test/by_method:methods.yaml`.

When using ``avocado run -m $location:$path`` the last node of the
$location has to preserve value/mux of the root of the parsed $path
file. Previously it was just a fresh node and all values/tags were
missing. This patch only renames the original parsed root and extend
the tree of the remaining $location nodes.

This patch modifies the multiplexer logic to support full recursive
multiplexation, unlike the old version which only flattened the
multiplexed nodes. This allows greater flexibility.

Additionally it removes the !join flag and inverts the logic to use !mux
instead. By default leaves are not multiplexed and all are part of the
current params. Users can specify exact nodes which get multiplexed by
using !mux keyword.
