Comment 6 for bug 1585506

Here is the RCA http://pastebin.com/d1W6GvgC, done keeping in mind the aforementioned 3 types of failures.

By results:
* Fatal ostf failures of "Type 3" are expected with the current cluster state, which is yet to be assembled after a cold restart. Fits to the SLA for a DB cluster recovery after a cold restart, which is from 5 to 20 min, IIRC
* ostf failures of "Type 2" are expected with the recent cluster state, which is 1 of 3 nodes is down, not fatal, just ignore this
* ostf failures of "Type 1" are in the scope for only A/A Galera, we use A/P, so not fatal, just ignore this

moving to invalid, and opening an OSTF bug for the Type 1 to be reworked
