Add ability to mock/fake time intervals in tests

System.nanoTime can't be mocked in tests. This change replaces
System.nanoTime with Ticker and adds the TestTicker for mocking.

Gerrit already has @UseClockStep annotiations, but it works with jgit
and can't be reused because it doesn't provide nanoseconds resolution.

This change adds minimal implementation which can be used in tests.
Later it can be extended with annotations and other features (or
combined with @UseClockStep).
