plugin on previously defined test. This gives a possibility to test
plugin in end-to-end variant.

Select and place common code of three adapters (HardwareAdapter,
BinaryAdapterBase and QemuAdapter) into basic DeviceAdapter class.
Introduce new way of reading device output by run separate thread which
try to read device output and place it into internal python queue.
Thanks to this, now it is possible to create readline method for all
adapters, which can be unblock when timeout occur.
Collect all common steps which have to be done before setup device in
launch method. The same was done for teardown operations which were
placed into close method.
Additionally some protection mechanisms were introduced to prevent for
undesirable side-effects when user could try to launch to already
launched device or try to send some data to disconnected device.
iter_stdout method was replaced by two new methods: readline and
readlines. To make it possible to remove all read output from internal
buffer (queue), clear_buffer method was introduced.
Also unit tests were rewritten to work properly with current version
of adapters.

Adding pytest plugin dedicated to running pytest tests in Zephyr
project. This plugin provides a dut fixture which allows to handle
bidirectional communication with the device under test. This version
of plugin can be used for tests dedicated to real hardware, QEMU and
native_posix simulator.
