dependencies (#1540)
We recently found Quartz jobs cannot easily inject a dependency. The previously proposal was to add dependencies into Context of Quartz Job. However, it is not recommended, the correct approach is to only inject String or very light weight objects into context. Besides, it increased more complexity for users to leverage Quartz. In this PR, we create a Quartz Job Factory, which is able to seamlessly provide any dependency inside web server.

a problem when a queued job would disappear from the job list view when its state changes to QUEUED.
Currently, you can access job logs for current and failed attempts in the Job List tab of an execution.
If some job failed and has retries, it goes into QUEUED state while sleeping before the next attempt.
If you want to see why any of the previous attempts failed, you can right-click the grey attempt bar
To see how long it's going to sleep, you can check the job log
Without this fix you can't do either of those if the job is sleeping, because it's hidden if the state is QUEUED.
Also if you have a job that hasn't yet started to run but is in QUEUED state (ie. blocked by pipeline), if you want to know why it's queued, you should check the job log. If you can't access the job log via Job List tab, this is not easily accomplished.

PR proposes bringing quartz to AZ. Quartz Scheduler provides 3 modes of job stores: RAMJobStore, JDBCJobStore, and TerraCottaJobStore. In order to persist the job statuses out of Application memory regardless of downtime, we recommend using JDBC JobStore. In fact, users can specify the mode in quartz properties.
This code patch creates Quartz server and manages Quartz API (e.g., start, pause, shut down) at class QuartzScheduler. We directly use h2-in-memory DB to directly test JDBC Quartz in unit test.
