[systest] improve system tests logs

[Aleksandra Fedorova]

Currently the only result we get in system tests output is this traceback:

FAIL: Deploy cluster in HA mode with Neutron GRE
----------------------------------------------------------------------
Traceback (most recent call last):

    task['status'], 'ready', name=task["name"]
AssertionError: Task 'deployment' has incorrect status. error != ready

which has no info about what has failed and why.

While in sys_test.log we have at least this message:

2014-04-18 06:22:37,445 - DEBUG __init__.py:50 -- Done: task_wait with result: {u'status': u'error', u'name': u'deployment', u'cluster': 1, u'result': {}, u'progress': 100, u'message': u"Deployment has failed. Check these nodes:\n'slave-02_compute', 'slave-01_controller'", u'id': 3, u'uuid': u'f74d1656-3ea0-43cc-b60c-3eb4a676c8de'}

I suggest we

1) remove the traceback from the output (do some nicer try-except and print only the error)
2) raise the severity of "Done: task_wait with result:" messages to INFO

My suggestion to use nice report tool, for example ya-allure. and all your problems will be solved.
