Add exception traceback to comment for failed steps

[dmncmn]

[Enhancement]
For greater clarity displayed 10 last lines of traceback in the comment below failed step:

Dummy scenario
->  given step_01 [passed]
->  given step_02 [failed]
...
  File "/my_tests/test.py", line 2, in <module>
->  given step_03 [skipped]
->  given step_04 [skipped]
