Cron like checking/scheduler Adding apscheduler

[dgtlmoon]

solution for #1092

• needs sqlite or similar (only should be enabled when this is setup?)
• needs to keep the item scheduled until it has ran (incase it gets scheduled but cdio restarted)

    async with AsyncScheduler(data_store) as scheduler:
        await scheduler.add_schedule(tick, IntervalTrigger(seconds=1), id="tick")
        await scheduler.run_until_stopped()

maybe interval trigger could be based on the current seconds/days/etc too

is in-memory-scheduler enough? pgsql/mysql etc not needed?

APScheduler has three built-in scheduling systems you can use:

• Cron-style scheduling (with optional start/end times)
• Interval-based execution (runs jobs on even intervals, with optional start/end times)
• One-off delayed execution (runs jobs once, on a set date/time)

use the interval based execution (what we have now) first
