This test was introduced in #12079, it works well most of the time, but occasionally fails: ``` 00:34:45> SENTINEL SIMULATE-FAILURE crash-after-election works: OK 00:34:45> SENTINEL SIMULATE-FAILURE crash-after-promotion works: FAILED: Sentinel set crash-after-promotion but did not exit ``` Don't know the reason, it may be affected by the exit of the previous crash-after-election test. Because it doesn't really make much sense to go deeper into it now, we re-source init-tests to get a clean environment before each test, to try to fix this. After applying this change, we found a new error: ``` 16:39:33> SENTINEL SIMULATE-FAILURE crash-after-election works: FAILED: caught an error in the test couldn't open socket: connection refused couldn't open socket: connection refused ``` I am guessing the sentinel triggers failover and exits before SENTINEL FAILOVER, added a new || condition in wait_for_condition to fix it.
