tests: add tests for OSPF GR unplanned outages

Browse Source 
Reuse the exiting GR topotests since planned and unplanned GR should
behave the same.

The only difference is that for unplanned GR there's no preparation
phase. The OSPF daemons are just killed (SIGTERM) and restarted
normally. The tests then proceed to do the same checks they do for
planned GRs.
