Review comment:
A few places changing this `logRollPeriod` from seconds to milliseconds.
It seems clearer to jut rename it to `logRollPeriodMs` and use values in
milliseconds.

Review comment:
I think the common faker timer would be better if we create a new public
constructor? Using `advance` would be more clearer when reading.
```
FakeTimer fakeTimer = new
FakeTimer(standby.getNamesystem().getEditLogTailer().getTimer().monotonicNow());
standby.getNamesystem().getEditLogTailer().setTimerForTest(fakerTimer);
...
fakeTimer.advance(inSufficientTimeForLogRoll);
try {
checkForLogRoll(active, origTxId, noLogRollWaitTime);
fail("Expected to timeout");
}
....
fakeTimer.advance(sufficientTimeForLogRoll);
checkForLogRoll(active, origTxId, logRollWaitTime);
```

Review comment:
It this the `testTimer.monotinicNow()`?
