L1 tests reboot device

[StepanVovkPLV]

Objective: if in collected tests we have at least one test_l1 we will sort the list with collected test items, and to the last test of the list(which will be last L1 test) we add additional fixture which will reboot device

• in def pytest_collection_modifyitems(session, config, items) will perform sorting of ALL the items based on the key provided
• in pytest_collection_finish(session) hook we will select last test within current session and set the test where to add reboot fixture
• in async def reboot_device(testbed) will perform reboot of the device
• in pytest_runtest_setup(item): we modify the last item in sorted session.items list and add rebot_device fixture

Can not perform onlpdump on the device. -> cmd not found
