89ffac3b01 testing: allow custom test cleanup handlers in pytest
In order to provide more flexibility for the test writers,
add per-test-method cleanups in addition to the per-class cleanups.

Now the test 'test_one' can perform cleanup by either defining
per-class 'cleanup' method (typically used in VNET classes) and
per-test method 'cleanup_test_one'. The latter has preference.
In order to handle paramatrization, testid is passed as a single
 argument to both of the methods.

513ce835b5 testing: pass ATF vars to pytest via env instead of arguments.
This change is a continuation of 9c42645a1e workaround.
Apparently pytest argument parser is not happy when parsing values
 with spaces or just more than one --atf-var argument.
Switch wrapper to send these kv pairs as env variables. Specifically,
 use _ATF_VAR_key=value format to distinguish from the other vars.

Add the `atf_vars` fixture returning all passed kv pairs as a dict.

8eb2bee6c0 testing: Add basic atf support to pytest.
Implementation consists of the pytest plugin implementing ATF format and
a simple C++ wrapper, which reorders the provided arguments from ATF format
to the format understandable by pytest. Each test has this wrapper specified
after the shebang. When kyua executes the test, wrapper calls pytest, which
loads atf plugin, does the work and returns the result. Additionally, a
separate python "package", `/usr/tests/atf_python` has been added to collect
code that may be useful across different tests.

Current limitations:
* Opaque metadata passing via X-Name properties. Require some fixtures to write
* `-s srcdir` parameter passed by the runner is ignored.
* No `atf-c-api(3)` or similar - relying on pytest framework & existing python libraries
* No support for `atf_tc_<get|has>_config_var()` & `atf_tc_set_md_var()`.
 Can be probably implemented with env variables & autoload fixtures
