Provide an implementation of re-entrant asyncio.run() that is less
brittle than what greenback provides (e.g. no use of ctypes to poke
extension types).
The general idea of the implementation consists in treating the executed
coroutine as a generator, then turning that generator into a generator
implemented using greenlet. This allows a nested function to make the
top-level parent yield values on its behalf, as if every call was
annotated with "yield from".

Default connection timeout (30 secs) may be insufficient for some test
setups or in some conditions. Thus, support specifying timeout parameter
in target configuration file.

We can mimic ChromeOS target by combining a QEMU guest (for Linux
bindings of ``ChromeOsTarget`` class) with a Android virtual desktop
(for Android bits of ``ChromeOsTarget``).
Note that Android bindings of ``ChromeOsTarget`` class also requires
existence of ``/opt/google/containers/android`` folder on the Linux
guest.

Add support for launching emulated targets on QEMU. The base class
``TargetRunner`` has groundwork for target runners like
``QEMUTargetRunner``.
``TargetRunner`` is a contextmanager which starts runner process (e.g.,
QEMU), makes sure the target is accessible over SSH (if
``connect=True``), and terminates the runner process once it's done.
The other newly introduced ``QEMUTargetRunner`` class:
- performs sanity checks to ensure QEMU executable, kernel, and initrd
images exist,
- builds QEMU parameters properly,
- creates ``Target`` object,
- and lets ``TargetRunner`` manage the QEMU instance.
Also add a new test case in ``tests/test_target.py`` to ensure devlib
can run a QEMU target and execute some basic commands on it.
While we are in neighborhood, fix a typo in ``Target.setup()``.

Test Android and Linux targets as well in addition to LocalLinux target.
In order to keep basic verification easy, list complete list of test
targets in tests/target_configs.yaml.example and keep the default
configuration file for targets simple.
Also:
- Create a test folder on target's working directory.
- Remove all devlib artefacts after execution of the test.
- Add logs to show progress of operations.

This will be useful in automating CI tests without modifying the source
code.
Replace unittest with pytest in order to make parameter passing to test
functions easier.
Move target configuration reading and generating target object outside
of the test function. Because we will run the test function for new
targets and may want to add new test functions.
While we are here, also fix pylint issues.

Extend Target.read_tree_values() to handle notes that contain line
breaks in their values. Underlying this method, is a call to
grep -r '' /tree/root/
When files under that location contain multiple lines, grep will output
each line prefixed with the path; e.g. a file "test" with the contents
"one\n\ntwo\n" will be output by grep as:
/tree/root/test: one
/tree/root/test:
/tree/root/test: two
Previous implementation of read_tree_values() was assuming one value per
line, and that the paths were unique. Since it wasn't checking for
duplicate paths, it would simply override the earlier entries resulting
with the value of "two" for test.
This change ensure that such multiline values are now handled correctly,
and the entire value is preserved.
To keep compatibility with existing uses of read_tree_values(), the
trailing new lines are stripped.
