[16/50] [abbrv] helix git commit: Test base refactoring and add new synchronize tests

Test base refactoring and add new synchronize tests

Due to heavy asynchronized tests running in Helix, current tests are running slow. Thus introduce these new synchronized tests to improve the test efficiency.
1. Split out TaskSynchronizedTestBase.
2. Add synchronized test for delay jobs.
