HBASE-19335 Fix waitUntilAllRegionsAssigned(). Ignore assignments to killed servers and when region state != OPEN. 

Update timeouts for TestRegionObserverInterface.
Reason: There are ~10 tests there, each with 5 min individual timeout. Too much. The test class is labelled MediumTests,
let's used that with our standard CategoryBasedTimeout. 3 min per test function should be enough even on slower Apache machines.
